A 2.0-kg cart moving to the right with a speed of 1.0 m/s has a head-on collision with a 4.0-kg cart that is initially moving to the left with a speed of 1.5 m/s. After the collision, the 2.0-kg cart is moving to the left with a speed of 0.5 m/s. What is the final velocity of the 4.0-kg cart? a) zero m/s Ob) 1.5 m/s to the right c) 1.5 m/s to the left d) 0.75 m/s to the right e) 0.75 m/s to the left

2. A skateboarder is traveling 7.32 m/s on a flat and level sidewalk. The mass of the board and rider is 63.0 kg. As she coasts along, she grabs a 8.55 kg backpack a friend is holding out. A) What properties are conserved in this problem? 8) What type of collision is this? Why? C) What is her speed after getting the backpack? D) Explain in words what would happen if the backpack where thrown at her?

A 0.060-kg tennis ball, moving with a speed of 5.82 m/s , has a head-on collision with a 0.090-kg ball initially moving in the same direction at a speed of 3.64 m/s . Assume that the collision is perfectly elastic. - Determine the speed and direction of the 0.060-kg ball after the collision. - Determine the speed and direction of the 0.090-kg ball after the collision

3. A 95.5-kg football player running north at 6.25 m/s is tackled by a 105-kg player running south at 4.90 m/s. If they stick together during the collision, what is the magnitude and direction of their velocity right after the collision?

A 15-kg green bowling ball moving eastward initially with a speed of 2.0 m/s makes an elastic head-on collision with a 9.0-kg red bowling ball that is moving westward at 3.0 m/s. Determine the final velocities of each bowling ball right after the collision.

On a frictionless, horizontal air table, puck A (with mass 0.250 kg) is moving toward puck B (with mass 0.350 kg), which is initially at rest. After the collision, puck A has a velocity of 0.120 m/s to the left, and puck B has a velocity of 0.640 m/s to the right. a)What was the speed of puck A before the collision? b)Calculate the change in the total kinetic energy of the system that occurs during the collision.

5. A 1-kg body moving forward at 5 m/s hits a second body at rest. After the collision, the 1-kg body reverses its direction and moves at 1 m/s while the second body moves forward at 2 m/s. What is the mass of the second body?

A ball of mass 0.240 kg that is moving with a speed of 5.7 m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.4 m/s. - Calculate the velocity of the target ball after the collision. - Calculate the mass of the target ball.
