2. (MOMENTUM AND IMPULSE) In Cases A and B illustrated below, identical balls collide
with a wall. In Case A, the ball strikes the wall head-on and bounces straight back, whereas
in Case B, the ball hits the wall at an angle. In both cases, the initial speed v, and final
speed vf of the ball are the same. Additionally, the ball in Case A has the same speed as
the ball in Case B.
