A 60-kg patient exercises on the treadmill, exerting a constant force of 500N while running at a constant velocity of 4m/s at an angle of the treadmill θ=30° for 5 minutes. The coefficient of kinetic friction of the treadmill is 0.45. Determine the work done by the patient.
[hint: use W = Fd=(T-mg sinθ - µkN)d]
