Water accelerated by a nozzle to 20 m/s strikes the vertical back surface of a cart moving horizontally at a constant velocity of 5 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 plane of the back surface. (a) Determine the force that needs to be applied by the breaks of the cart to prevent it from accelerating. (b) If this force were used to generate power instead of wasting it on the breaks, determine the maximum amount of power that could be ideally generated.
