In the figure below, the net external force on the 22 kg mower is given as 55 N. If the force of friction opposing the motion is 26 N, what force F (in N) is the person exerting on the mower? (Enter the magnitude.) N Suppose the mower is moving at 1.5 m/s when the force F is removed. How far (in m) will the mower go before stopping? m
