2. A one-dimensional collision occurs between a cart of mass 12 kg moving to the right at 3 m/s and a block of mass 4 kg moving to the left at 12 m/s. After the collision, the 4 kg block moves to the right at 3 m/s. a. What is the velocity of the cart after the collision? b. If the collision lasts 0.020 s, find the average force on the cart? c. Find the average force the cart exerts on the block during the collision. d. How much kinetic energy is lost during the collision? This lost kinetic energy is converted to thermal energy and the energy carried by the sound waves.

1. The dynamics TAs want to do an experiment with bowling balls to figure out their velocity after colliding. Bowling ball A has a mass of 3kg and is moving at 8 m/s to the right and it makes a direct collision with bowling ball B, which has a mass of 2 kg and is moving 4 m/s to the left. If e=0.7, what is the velocity and direction of each bowling ball just after the collision. You can neglect the size of the bowling balls. [Ans. To Check: va=0.16m/s←] 8 m/s 4m/s B
