Answer:

-47.04

Explanation:

Divide 12 m by 2.5 m/s which equals 4.8s

And then use 4.8s to multiply it with -9.8

4.8(-9.8)= -47.04 m/s

Hope this helped!! :)

The initial height of the pumpkin is 23.52m and the final vertical velocity of the pumpkin is 47.04 m/s.

Initial horizontal speed, u = 2.5 m/s

horizontal distance covered , d = 12m

So the time taken is:

t = d/u

t = 12/2.5 s

t = 4.8s

Now, the initial vertical speed, v = 0

So the vertical distance traveled by the pumpkin will be equal to the initial height of the pumpkin:

s = vt + ¹/₂gt²

s = 0.5 × 9.8 × 4.8 m

s = 23.52m

Final vertical velocity:

v' = v + gt

v' = 9.8 × 4.8 m/s

v' = 47.04 m/s

Answer  888990,0 kg

Explanation:

888990,0 kg is the mass of the object.

Any two mass-containing objects are attracted to one another by the gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive.

Newton's Universal Law of Gravitation is what it is known as.

Admittedly, you aren't pushing on those other objects all that much because you don't have a very large mass. Additionally, items that are very far apart from one another do not clearly tug on one another. 

Therefore, 888990,0 kg is the mass of the object.

Answer:

2.625 m/s

Explanation:

This is a momentum question. Momentum is conserved which means that all the starting momentum must be accounted for.

1.5 kg * 2 m/s + 2.5 kg * 3 m's = (1.5 + 2.5)kg * x m/s

3 kg m/s + 7.5 kg m/s = 4 kg * x

10.5 kg m/s = 4 kg x

10.5 / 4 = x

x = 2.625 m/s

inelastic means that after the collision, the masses stick together as though they were one.

A baseball bat is a lever. Which of the following explains how a baseball bat differs from a lever like a pry bar?

A) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a long distance.

B) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a short distance.

C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.

D) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a short distance.

Answer:

C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.

Explanation:

The correct answer is option C. This is because unlike in a pry bar, the effort force when swinging a baseball bat is larger and it is applied over a short distance; and in return the resisting force is smaller and it's applied over a long distance.

3

The biggest offspring will be selected and bred together.

4

This cycle continues until the dogs have been selectively bred to be bigger than the current world record size.

5

Selective breeders need to ensure that they are not also selecting for disadvantageous traits, like genetic limb defects.

Geological and atmospheric changes happening over a long time scale can cause short extinctions.

Explanation:

When the south pole of a bar magnet is near the north pole of another bar magnet, they move toward each other. Therefore, option (C) is correct.

A magnet can be described as a substance that creates a magnetic field and this magnetic field is the reason for the considerable properties of a magnet. The magnetic force pulls ferromagnetic materials, such as iron, cobalt, etc., and attracts or repels other magnetic substances.

A permanent magnet is composed of a material that is magnetized and produces its own magnetic field such material can be magnetized, and strongly attracted towards a magnet, is known as ferromagnetic, and contain the elements iron, and cobalt.

Each bar magnet possesses a set of North and South poles within them. The south pole of one magnet brings closer to the north pole of another magnet they attract each other and move toward each other.

Explanation:

Inertia is the tendency of a body to remain at rest or to do nothing.

It is the resistance to any change in position of body.

 When the force on a body increases, the inertia reduces

 When the mass is reduced the inertia reduces

According to newton's first law or the law of inertia "an object will remain in its state of rest or of uniform motion unless if it is acted upon by an external force".

Answer:

You would have to find the friction force of the rubber block which would be found with the equation of Normal force (mass*gravity) times cooeficient of friction which would give 8.82 N for the amount of friction and because you need more force than 8.82 N (assuming gravity is 9.8)

We need to find the frictional force of the rubber block. This is the normal force (mass × gravity) multiplied by the coefficient of friction, which gives us a friction quantity of 8.82N. This is because it requires a force greater than 8.82N (Gravity is 9.8)

Answer:

The final speed is 75 m/s

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes uniformly in time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

[tex]v_f=v_o+at[/tex]

The airplane comes from rest (vo=0) accelerating at a=25 m/s^2 for t=3 s.

The final speed is:

[tex]v_f=0+25~m/s^2\cdot 3~s[/tex]

[tex]v_f=75~m/s[/tex]

The final speed is 75 m/s

My commute to school is a constant distance, but the time it takes to get there fluctuates owing to traffic.

If an object moves with respect to a reference frame, such as when a passenger travels to the back of an airliner or a professor moves to the right with respect to a whiteboard, the item's position changes.

This change in location is described as displacement.

My commute to school is a constant distance, but the time it takes to get there fluctuates owing to traffic,

Answer:

Force of kinetic friction, Fk = 6N

Explanation:

Given the following data;

Coefficient of kinetic friction, μ = 0.2

Normal force, Fn=30N

To find the Force of kinetic friction;

Mathematically, the force of kinetic friction is given by the formula;

Fk = μFn

Where;

Substituting into the equation, we have;

Fk = 0.2*30

Fk = 6N

Therefore, the force of kinetic friction is 6N.

A force that is present between two moving objects or surfaces is called kinetic friction. It is estimated in newtons (N) and is calculated by:

[tex]\rm F_{k} =\rm \mu _{\rm k} F_{n}[/tex]

Where, [tex]\rm F_{k}[/tex] = frictional force,  [tex]\mu _{\rm k}[/tex]  = coefficient, [tex]\rm F_{n}[/tex] = normal force.

The kinetic friction of the object is 6N.

The kinetic friction can be estimated as:

Given,

Substituting values in the formula:

[tex]\rm F_{k} =\rm \mu _{\rm k} F_{n}[/tex]

[tex]\begin{aligned}\rm F_{k} &= 0.2 \times 30\\\\\rm F_{k} &= 6 \rm N\end{aligned}[/tex]

Therefore, 6N is the frictional force.

When a wire moves through a magnetic field, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.

A magnetic field is a region in space where a magnetic force can be detected, so when a wire moves through a magnetic field, the magnetic force exerted on the wire generates a voltage, and the voltage creates an electric current in the wire. This electromagnetic induction phenomenon occurs because of the movement of charged particles within the wire, and this phenomenon can be explained by Faraday's Law of Electromagnetic Induction.
