While playing pingpong, a person spikes the ball and it hits the horizontal table at an angle of 57.5 degrees to the normal and with an initial speed of 11.7 m/s. If it bounces off at the same angle with the normal, and at the same speed, what impulse does the table impart to the ball? Assume the ball has a mass of 7.75 grams.
