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.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
