A constant 112.-N force acts on a 3.81-kg box. The box initially is moving at 24.9 m/s in the direction of the force, and 3.72 s later the box is moving at 71.1 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.
