The handle of a 22 kg lawnmower makes a 33-degree angle with the horizontal. If the coefficient of friction between lawnmower and ground is 0.62, what magnitude of force is required to push the mower at constant velocity? Assume the force is applied in the direction of the handle.

Justin R asked:
A person exerts a force of 120 N at an angle of 40 degrees on a lawn mower handle as they push the mower. If the mower moves at 1.75 m/s, how much power is used by the person to move the mower?
