A tennis player hits a serve for an ace. The length from their shoulder to their hand was 1.01 m and the length of their racket (from grip to ball contact point) is 0.31 m. During the service motion, they accelerated their shoulder at 2,290 deg/s^2 and went through a range of motion of 131 degrees. What was the linear velocity of the ball in the instant after contact? (remember to convert to radians). Assume a perfect energy transfer between racket and ball (i.e. no 'trampoline' effect from the strings).
