Imagine a person dragging a 50 kg box along the ground with a rope. The person exerts 50 N of force while moving the box 20 m in 10 s. Suppose also that friction is acting with 30 N of force between the box and the ground.
For the box in question determine
a. the total work done on the box
b. the change in the box’s kinetic energy
c. the speed of the box at the end of its 20 m trip if it started from rest.
