a 60-kg patient exercise on the treadmill, exerting a constant force of 500N while running at a constant velocity of 4 m/s at an angle of 30 for 5 minutes. the coefficient of kinetic friction of the treadmill os 0.45. determine the work done by the patient.

Answer 1

The coefficient of kinetic friction has nothing to do with the work done. His shoes are not sliding on the treadmill.

Work = (Force exerted) x velocity x time

You don't need to know his mass or the angle of the ramp. Just the force.

The force required is a function of the slope and his weight, but they have already told you what the force is. So use it
