The tennis ball has a horizontal speed of 15 m/s when struck by the racket. If it then travels away at an angle of 25 degrees from the horizontal and reaches a maximum altitude of 10m, measured from the height of the racket, determine the magnitude of the net impulse of the racket on the ball. The ball has a mass of 180g. Neglect the weight of the ball during the time the racket strikes the ball.© BrainMass Inc. brainmass.com March 4, 2021, 6:06 pm ad1c9bdddf
First, we calculate the vertical velocity v1 of the ball:
From equation ...
