A student using an air track with two carts records the result of an inelastic collision. One cart has a mass of 0.2 kg and the other a mass of 0.4 kg. They moved off together at 0.2 m/s after the collision. The 0.4 kg cart was initially at rest. What was the final momentum of the carts?

A car of mass 1388 kg traveling at 18.67 m/s Collided and sticks to another car with a mass of 1488 kg. what is the resulting velocity of the two cars right after the collision assuming that there is no friction present?

A 7-kg object moving with a velocity of 5 m/s in the positive x direction strikes and sticks to a 2-kg object moving with a speed of 1 m/s in the same direction. What is their speed after the collision?

A 10 kg cart is traveling at a velocity of 4 m/s in the rightward direction. It strikes a 7 kg cart also traveling at 6 m/s also in the rightward direction. The carts stick together after impact. What is the final velocity of the two-cart system?

A 51 kg boy on roller skates moves with a speed of 3 m/s. He runs into a 42 kg girl on skates. Assuming they cling together after the collision, what is their speed (in m/s)? (Assume the girl is initially at rest.) m/s

A 10.50-g bullet is fired into a stationary block of wood having mass m = 4.980 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.6090 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)  m/s

A glider with the mass of 225g has the velocity of 60.36cm/s. It collided inelastically with 190g stationary glider. Their combined velocity after the collision is measured to be 30.2cm/s. What is the momentum before and after the collision?

A baseball pitch was recorded at 105.1 mph, which is 46.98 meters per second. The mass of the ball is 0.14 kg. Part 1- What is the impulse that is required to give the baseball such momentum? Part 2- What is the impulse that is required by the catcher to be able to stop the ball? Part 3- If the impulse from part 2 was applied to the ball over 0.20 seconds, what is the magnitude of the force acting between the catchers mitt and the ball?

A green pool ball (p = 30 kg x m/s) moves towards a yellow pool ball (p = -9 kg x m/s).  Then, the two pool balls collide.  After the collision, the green pool ball has a momentum of 3 kg x m/s.   How much momentum does the yellow pool ball have after the collision?  Explain your answer.

Two clay balls collide and stick. Ball 1 has a mass of 3 kg and an initial velocity of 10 m/s in the positive x direction. Ball 2 has a mass of 10 kg and an initial velocity of 12 m/s in the negative x direction. What is the final velocity of the combined mass?
