During a tennis serve, a racket is given an angular acceleration of magnitude 140 rad/s2. At the top of the serve, the racket has an angular speed of 20.0 rad/s. If the distance between the top of the racket and the shoulder is 1.00 m, find the magnitude of the total acceleration of the top of the racket.

3a. A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.00×1041.00×104 rad/s to an angular speed of 3.30×1043.30×104 rad/s. In the process, the bit turns through 1.86×1041.86×104 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 7.80×1047.80×104 rad/s, starting from rest? ________s 3b.

7. On a serve, a tennis ball may leave the tennis racket of a top player at a speed of 65.0 m/s. If the ball has a mass of 0.0600 kg and it is in contact with the racket for 0.0300 seconds, what is the average force applied to the ball? Would that be enough force to lift an average size person (75 kg)? Assume that the tennis ball is initially not moving
