1) A stream of water strikes a stationary turbine blade horizontally as shown below. The incident water stream has a velocity of +16.0 m/s and the exiting stream has a velocity of -16.0 m/s. the mass of water per second that strikes the blade is 30.0 kg/s. Find the Magnitude of the average force exerted by the blade of water.
2) a golf ball strikes a hard, smooth surface at an angle of 30.0 degrees and rebounds at the same angle. The mass of the ball is 0.047 kg and has a speed of 45 m/s just before and after striking the surface. what is the impulse applied to the golf ball by the surface?
