How much power is needed to move the lawn mower with 120 N of force exerted?

By admin | September 9, 2008

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?

      P = Fv
      P = 120(cos40)(1.75)
      P = 161 W
