You are going to race your friend to a tree near the back of the playground. The tree is 24 meters away from where you stand. It will take you 4 seconds to reach the tree. What will your average speed be?
Answer:
1. 6 m/s.
2. 320 miles.
Explanation:
1. Determination of the average speed.
Total distance travelled (D) = 24 m
Total time (t) = 4 s
Average speed =.?
Average speed is simply defined:
Average speed = Total distance /total time
Average speed = 24/4
Average speed = 6 m/s
2. Determination of the distance travelled by the train.
Speed = 40 mph
Time = 8 h
Distance =?
Speed is simply defined as:
Speed = Distance /time
40 = Distance / 8
Cross multiply
Distance = 40 × 8
Distance = 320 miles
Therefore, the train travels a distance of 320 miles.

A player punts a football at an angle of 30 degrees. The football has an initial
velocity of 20.0 m/s. Find the y-component of the ball's velocity.
17.3 m/s
O 10.0 m/s
O 30.0 m/s
0 25.1 m/s
Answer:
The y-component of the ball's velocity is 10 m/s
The second choice 10.0 m/s is correct
Explanation:
Projectile Motion
It's the type of motion that experiences an object that is projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
Being vo the magnitude of the initial velocity and θ the angle it makes with the horizontal, the components of the initial velocity are calculated as follows:
[tex]v_{ox}=v_o.\cos\theta[/tex]
[tex]v_{oy}=v_o.\sin\theta[/tex]
Since the football is kicked at vo=20 m/s and an angle of θ=30°:
[tex]v_{oy}=20.\sin 30^\circ[/tex]
[tex]v_{oy}=20*0.5=10[/tex]
The y-component of the ball's velocity is 10 m/s
The second choice 10.0 m/s is correct
why does nobody love me?
Answer: I’m sure theirs people out there that like you, and if there isn’t, you should just focus on yourself.
Explanation:
Answer:
Well, There are a couple reasons it could seem like nobody loves you...
Explanation:
One reason is that people really do love you, they just were never shown love and affection so they are unsure of how to show that to you. Another reason could be that it's god telling you that you are meant for much bigger and greater things. Maybe it's him reminding you that, yeah, people really suck, but that's life, and you're better than that. If you make the right decisions in life, you will be able to stand taller than they ever did. I hope this helps.. : )

Miguel added 150 grams of baking soda to a liter of water at 20 °C. No matter how long he keeps stirring the solution, he can’t get all of the baking soda to dissolve. Explain why.
Answer:
See the answer below
Explanation:
This is because, at 20 °C, the solution has become saturated with the baking soda.
The solubility of a substance is the maximum amount of that substance that will dissolve in a particular solvent at a given temperature. The solubility of a substance generally increases with an increase in temperature.
At 20 °C temperature, the maximum amount of baking soda that can dissolve in a liter of water has been exceeded by Miguel. Hence, no matter how hard he tries to stir the solution, the excess baking soda will not dissolve.
The reason he can’t get all of the baking soda to dissolve is; because at 20 °C, the solution has become saturated with the baking soda.
What is a saturated solution?For us to say a substance is soluble, it means that the maximum amount of that substance will dissolve in a particular solvent at a given temperature. Thus, the solubility of a substance is said increase with a corresponding increase in temperature.
From the question, at 20 °C temperature, miguel has exceeded the maximum amount of baking soda that can dissolve in a liter of water. Therefore, no matter how hard he tries to stir the solution, it will not dissolve due to the excess soda.

A car on flat ground accelerates at 0.785 m/s2 when a net force of 1050 N acts on it. How much normal force acts on it?
Answer:
13108.3N
Explanation:
Given parameters:
Acceleration = 0.785m/s²
Net force = 1050N
Unknown:
Normal force acting on car = ?
Solution:
The normal force on this car is the weight of the car;
Normal force = mg
where m is the mass of the car
g is the acceleration due to gravity = 9.8m/s²
Now solve for the mass;
Net force = mass x acceleration
1050 = mass x 0.785
mass = [tex]\frac{1050}{0.785}[/tex] = 1337.6kg
So,
Normal force = 1337.6kg x 9.8m/s² = 13108.3N

The weight of a box is having a mass of 100 kg is ___n
Answer: the weight of the box is 980N
Explanation:
The weight an object has is defined as the force of gravity acting on that object which is given as
w =m x g
Since weight is defined as a force, it can also be written as
w=mg
= F= mg
where m= mass of the object in kg given as 100Kg
an g is the gravitational acceleration in m/s^2 = g is 9.8 m/s2
F= mg
F = 100 kg x 9.8 m/s2
F== 980Kgm/s^2 = 980N
Therefore the weight of the box is 980N
Use the principle of superposition (Equation 1.3) to predict the electric field at the point 0.5 meters to the right and 1.5 meters above the 5 nC charge. Express your result both in terms of x and y components, and then in terms of total magnitude and direction.
Answer:
Explanation:
The x component of electric field Ex = k Q / R²
= 9 x 10⁹ x 5 x 10⁻⁹ / .5²
= 180 N .
The y component of electric field Ey = k Q / R²
The y component of electric field Ey
= 9 x 10⁹ x 5 x 10⁻⁹ / 1.5²
= 20 N
Total field = [tex]\sqrt{180^2+20^2}[/tex]
= 181.1 N .
Angle with x axis = Tanθ = Ey / Ex = 20 / 180 = .111
= 6.33⁰

F all of the energy in a falling object's gravitational potential energy store is transferred to its kinetic energy store by the time it lands, then the relationship shown below can be used. Which of the four options below it correctly shows how this relationship can be expressed in terms of height, h?
Answer:
The options are not shown, so let's derive the relationship.
For an object that is at a height H above the ground, and is not moving, the potential energy will be:
U = m*g*H
where m is the mass of the object, and g is the gravitational acceleration.
Now, the kinetic energy of an object can be written as:
K = (1/2)*m*v^2
where v is the velocity.
Now, when we drop the object, the potential energy begins to transform into kinetic energy, and by the conservation of the energy, by the moment that H is equal to zero (So the potential energy is zero) all the initial potential energy must now be converted into kinetic energy.
Uinitial = Kfinal.
m*g*H = (1/2)*m*v^2
v^2 = 2*g*H
v = √(2*g*H)
So we expressed the final velocity (the velocity at which the object impacts the ground) in terms of the height, H.

A trebuchet at ground levels throws a boulder with an initial velocity of 25 m/s at 30 degrees.
What was the magnitude of the final velocity of the boulder before it hit the ground?
a
30 m/s
b
10 m/s
C С
25 m/s
ОООООО
d
20 m/s
e
27.5 m/s
12.5 m/s
Answer:
The correct option is;
C. 25 m/s
Explanation:
The initial velocity with which the boulder was thrown = 25 m/s
The path in which the boulder projectile moves = 30°
For projectile motion, we have;
The time it takes the boulder to hit the ground is given by the following equation;
y = y₀ + v₀·sin(θ₀)t -¹/₂·g·t²
Where;
y = The height of the boulder
y₀ = The initial height of the boulder = 0
g = The acceleration due to gravity = 9.81 m/s²
When the boulder touches the ground again, the value of y = 0. therefore, we have;
0 = 0 + 25 × sin(30)t -¹/₂ × 9.81 × t²= 12.5·t - 4.905·t²
From which we have, t = 0 or t ≈ 2.55 s
At t = 2.55 s The vertical velocity = v₀sin(θ₀) - g·t = 25 × 0.5 - 9.81×2.55 = -12.5 m/s
The vertical velocity, [tex]v_y[/tex] = -12.5 m/s
The horizontal velocity, vₓ = v₀·cos(θ₀) = 25×cos(30) ≈ 21.65 m/s
The magnitude of the resultant velocity before, the boulder hits the ground is given as follows
[tex]\left | v \right |[/tex] = √((vₓ)² + ([tex]v_y[/tex])²) = √(12.5² + 21.65²) = √625 = 25
The magnitude of the resultant velocity before, the boulder hits the ground is 25 m/c
