A 2 kg ball is moving with a velocity of 5 m/s. What is the momentum of the ball?
2
A force of 20 N acts on a body for 3 seconds. What is the impulse given to the body?
3
Two ice skaters, one with a mass of 50 kg and the other with a mass of 70 kg, push off each other while on ice. If the skater with mass 50 kg moves with a velocity of 4 m/s, what is the velocity of the second skater after the push?
4
A 1.5 kg object is dropped from a height of 10 m. What is the object's velocity just before it hits the ground, assuming no air resistance? (Take g=9.8m/s2)
5
A 1 kg ball moving at 3 m/s collides elastically with a stationary 2 kg ball. After the collision, the 1 kg ball moves with a velocity of 1 m/s. What is the velocity of the 2 kg ball after the collision?
6
A 3 kg car moving at 6 m/s collides inelastically with a 2 kg car at rest. After the collision, both cars move together. What is the velocity of the combined system?
7
A 0.5 kg ball is thrown against a wall with a velocity of 4 m/s. The ball bounces off the wall with the same speed but in the opposite direction. What is the impulse exerted on the ball by the wall?
8
A 0.8 kg ice skater is initially at rest. A horizontal force of 5 N acts on the skater for 4 seconds. After the force is applied, the skater moves with a velocity of 3 m/s. What is the impulse exerted on the skater during this time?

A 0.5 kg ball moving at 6 m/s collides elastically with a 1.5 kg ball initially at rest. After the collision, the 0.5 kg ball moves with a velocity of 2 m/s in the opposite direction. What is the final velocity of the 1.5 kg ball after the collision?
10
A 4 kg block moving with a velocity of 3 m/s collides inelastically with a stationary 6 kg block. After the collision, the two blocks stick together and move as a single object. What is their common velocity after the collision?
