Water accelerated by a nozzle to 35 m/s strikes the vertical back surface of a cart moving horizontally at a constant velocity of 10 m/s in the flow direction. The mass flow rate of water through the stationary nozzle is 30 kg/s. After the strike, the water stream splatters off in all directions in the plane of the back surface.

(a) Determine the force that needs to be applied by the brakes of the cart to prevent it from accelerating.

(b) If this force were used to generate power instead of wasting it on the brakes, determine the maximum amount of power that could ideally be generated.
