5. What is the amount of work done when JoAnne throws a baseball 6.5 meters at a force of 40 newtons?

  W = 260 J

Explanation:

Work is defined by

          W = F. d

Bold type indicates vectors,

          W = F d cos θ

where tea is the angle between the force and the displacement, in this case the force is parallel to the displacement so the angle is zero and the

          cos 0=1

let's calculate

           W = 40 6.5

           W = 260 J
