1. A 10.0kg lab cart, A, is pushed at 6.00m/s directly toward a 20.0kg lab cart, B, moving the opposite direction at 15.0m/s. The two carts collide and and cart A rebounds at 22.0 m/s.

A. What is the velocity of cart B after the collision?

B. What is the force applied to cart B if the collision lasted for 0.250s?

C. Is the collision elastic or inelastic. A statement is not enough, you must show mathematical proof. 2. A 10.0kg cart, A, collides with a 7.50kg cart, B traveling at 3.00 m/s North. The two carts collide and stick together such that they are traveling 4.00 m/s at an angle of 105^o.

A. Calculate the magnitude of cart A's velocity before the collision.

B. Calculate the direction of cart A before the collision. 3. A 0.3 kg ball is thrown against a wall with the force on the ball represented by the graph above. Determine the magnitude of the impulse imparted to the ball.
