      Aug 12, 2011 · The ball is in contact with the strings of the racquet for 12 milliseconds. Find (a) the magnitude and direction of the average impulse exerted on the ball by the strings of the racquet, and (b) the magnitude of the average acceleration of the ball while it is in contact with the strings. Solution:
