How much power is needed to move the lawn mower with 120 N of force exerted?
By admin | September 9, 2008
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?
