Problem 8: A young 33-kg ice hockey goalie, originally at rest, catches a (0.13-kg hockey puck slapped at him at a spccd of 36.5 m/s. In this problem, take the original direction of the puck as positive. Part (a) Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would the final velocity of the puck, in meters per second, be in this case?

Block A (m=2.5kg) and Block B(m=3.5 kg, to the right of A) move on a frictionless horizontal surface. Initially, Blocl A is moving to the right st 6 m/s and Block B moves to the left with unknown speed. They collide head-on in a perfectly elastic collision. After the collision, block B moves to the right with a speed of 4.5 m/s. A) Find the speed of block B before the collision B)What is the velocity (magnitude and direction) of block A after collision?

A cue ball at rest on a frictionless pool table is hit dead center by a pool stick, giving it an impulse of +1.85 N · s. The ball slides (the combination of hitting the ball dead center and no friction allows this to happen) along the table and makes a head-on elastic collision with another pool ball. If both pool balls have a mass of 0.156 kg, determine the velocity (in m/s) of the second ball the instant after the collision.

A 0.250 kg hammer is moving horizontally at 4.50 m/s when it strikes a nail and comes to rest after driving it 1.00 cm into a board.(a) Calculate the duration of the impact....................s(b) What was the average force exerted on the nail?...................N

A steel ball of mass 0.600 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal. At the bottom of its path, the ball strikes a 3.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. (a) Find the speed of the ball just after collision. (No Response) m/s (b) Find the speed of the block just after collision. (No Response) m/s
