Question

A 0.060-kg tennis ball, moving with a speed of 5.3 m/s , has a head-on collision with a 8.5×10−2-kg ball initially moving in the same direction at a speed of 3.1 m/s .

Part A Assuming a perfectly elastic collision, determine the speed of each ball after the collision. Enter your answers numerically separated by a comma. Express your answers using two significant figures. v′tennis ball v t e n n i s b a l l ′ , v′ball = nothing m/s

Determine the direction of tennis ball after the collision.

A)The tennis ball moves in the direction of its initial motion.

B)The tennis ball moves in opposite direction.
