How Much Power Is Needed To Move The Lawn Mower With 120 N Of Force Exerted?
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
