A 0.3 kg book is struck with a force of 150 N If the ball was in contact with the ball for 0.02 s What is the ball's velocity?

To solve this problem we use the impulse momentum theory that tells us that the change in the momentum of an object (its mass times its velocity) is equal to the impulse that acts on it (a force multiplied by a time). Applying this theory to this problem we get the equation
.3kg * v = 150N * 0.02s.
Solving this equation for v we get that v must equal 10 m/s, which is therefore the new speed of the ball.

What is the effect of gravity on velocity?
Gravity is a force and any force acting on a body changes its velocity in the direction of the force.
Is elastic force a contact force or a non- contact force?
A spring force is a contact force not a non-contact force.
Differences between contact force and non contact force?
A non-contact force is any force applied o an object by another body that is not in direct contact with it,while A contact force is a force applied to a body by another body that is in contact with it. however it is to be noted that the origin of all contact forces can be traced to non-contact force.
Type of force that can change the velocity of a body at rest or in motion?
Any force will cause change in velocity if it isn't canceled by an equal, opposite force.
Why the force and velocity are in perpendicular direction?
In general, force and velocity do not have to be in the same direction; they can be at any angle.
What does gravity have to do with the game of pool?
The force of gravity affects how fast a ball travels after it has been hit. Gravity tends to pull the balls towards the center of the pool table when the balls are struck. Gravity tends to pull the balls towards the center of the pool table when the balls are struck.
Suppose you throw two balls at a wall The first ball sticks and the second bounces back with equal speed which ball struck the wall with a greater force?
Force is not relevant. The balls were made of different substances.
What is the effect of gravity on velocity?
Gravity is a force and any force acting on a body changes its velocity in the direction of the force.
Is elastic force a contact force or a non- contact force?

When does a force change the velocity of an object?
If the object is in free-space, and any force applied over a period of time will change the velocity of an object. Force = mass * acceleration. Acceleration = velocity / time. Therefore, Force = mass * velocity/time.
Type of force that can change the velocity of a body at rest or in motion?
Any force will cause change in velocity if it isn't canceled by an equal, opposite force.
How do you figure terminal velocity?
That's the velocity at which the force of air resistance is equal to the force of gravity.
Why the force and velocity are in perpendicular direction?
In general, force and velocity do not have to be in the same direction; they can be at any angle.
What is the velocity on an object with no net force?
When there is no resultant force there is no acceleration therefore the velocity will stay the same.
How is force a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.
Why balls reduce speed when it ascends higher?
As a ball goes up, the force of gravity is acting on it. The force of gravity means that acceleration in the upward direction is negative (and thus positive in the downward direction). The upward velocity of the ball decreases until it reaches zero - then ball begins to descend with increasing downward velocity.
