5. (4 pts.) Naomi Osaka recently won the 2020 US Open Tennis Championship, marking her third Grand Slam Victory. In the 2016 US Open, Osaka recorded her fastest serve at 125 mph. Let us make the following, rather brazen, assumptions: 0 This velocity represents the ball's tangential velocity as it left the racket, 0 This velocity was all generated by her shoulder joint, 0 Her shoulder rotational velocity was constant during the serve, and 0 Her arm and the tennis racket formed a single rigid segment that measured 101.9 cm from shoulder joint to where the racket struck the ball Given these assumptions, what was the angular velocity of her arm about the shoulder and what were the tangential and radial accelerations of the ball as it left the racket during her fastest recorded serve? Tangential velocity of ball (in m/s): Shoulder angular velocity: Tangential acceleration of the ball: Radial acceleration of the ball
