A 20 kg box has an initial velocity of 2 m/s starting at the bottom of a 30-degree inclined plane. A person pushes on the box directly up the inclined plane so that it travels up the inclined plane at a constant velocity of 2 m/s. If the coefficient of friction is 0.2 and the person pushes hard enough to maintain that constant 2 m/s, calculate how much work is done by the person after 5 seconds have passed
