Question

A volleyball player hit a ball with a mass of 0.25 kg. The average acceleration of the ball was 15.5 m/s². How much force did the volleyball player apply to the ball? A. 3.87 m/s² B. 62.0 m/s² C. 3.87 N D. 62.0 N

Answer 1

Force can be obtained by multiplying the mass of the object times the acceleration. Since all of the needed values are given, solving is done as shown below:

Force = mass x acceleration

Force = 0.25 kg x 15.5 m/s^2
Force = 3.875 N

Among the choices, the correct answer is C. 3.87 N

Answer 2

There must be movement for there to be work when a force is applied.
