Question

A 0.276-kg volleyball approaches a player horizontally with a speed of 15.4 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.6 m/s.

Answer 1

The question involves a change in a volleyball's speed due to a player's action, demonstrating the conservation of momentum principle in Physics.

Step-by-step explanation:

The question relates to a physical interaction between a volleyball and a player where the ball's speed and direction are changed due to the impact. This is an example of the conservation of momentum in collisions, a key concept in high school Physics. The equation for conservation of momentum is m1v1 + m2v2 = m1v1' + m2v2', where m is mass, v is initial velocity, v' is final velocity, and the subscripts 1 and 2 refer to different objects.
