A 0.060-kg tennis ball, moving by a speed of5.44m/s , has a head-on collision with a 0.080-kg ball initially moving in the same direction at a speed of 3.80m/s . Suppose that the collision is perfectly elastic.
Part A
Decide the speed of the 0.060-kg ball after the collision
Part B
Decide the speed of the 0.080-kg ball after the collision
