A constant 89.3-N force acts on a 3.49-kg box. The box initially is moving at 20.5 m/s in the direction of the force, and 4.44 s later the box is moving at 65.2 m/s. Determine the work (in J) done by this force. You may assume that the box experiences constant acceleration, but do not assume that only one force acts on the box.
