A 4.0-cm-diameter nozzle delivers a jet of water that strikes a flat plate normally. If the water speed is 50.0 m/s, calculate the force acting on the plate if (a) the plate is stationary, and if (b) the plate moves at 20 m/s in the same direction of the jet.

A jet of water 8 cm in diameter strikes a vertical plate perpendicularly with a velocity of 10 m/s. The plate is moving toward the jet with a velocity of 5 m/s. Determine the force and power required to move this plate.
