Question

Quizplus · Accepted Answer

When a tennis ball is thrown against the floor at an angle, the direction of the vertical component of its velocity reverses upon impact with the floor, while the horizontal component remains unchanged. This is due to the normal force from the floor acting perpendicular to the surface, which only affects the vertical motion.
