A 0.15 kg ball moving at 40 m/s is struck by a bat. The bat reverses the ball's direction and gives it a speed of 50 m/s. What average force does the bat apply to the ball if they are in contact for 6.0 ×10 ^-3 s?

		14 N
		2.5 × 10² N
		1.3 × 10³ N
		2.3 × 10³ N

A billiard ball moving at 5 m/s strikes a stationary ball of the same mass. After the collision, the original ball moves at a velocity of 4.35 m/s at an angle of 30 ^o below its original motion. Find the velocity and angle of the second ball after the collision.

		1.25 m/s @ 31.2^o
		1.44 m/s @ 60.0^o
		2.16 m/s @ 30.0^o
		2.47 m/s @ 61.9^o
