Question
A cragte of mass 25 kg is pushed up a ramp by a person as shown in the figure as per attachment. The person pushes the crate a distance of 27m as measured along the ramp. Assume the crate moves at constant velocity. Assume the coefficient of kinetic friction between the crate and the ramp is Uk = 0.37. What is the work done by the person as he pushes the crate up the ramp? J
