Q1. A tennis ball is served at 73.12 m/s and was in contact with the racquet for .027 s and starts from rest. The ball has an acceleration of 2730 m/s^2. Compute the distance travelled by the ball throughout the serve.

Q2. A pipe open only at one end has a fundamental frequency of 214 Hz. A second pipe, initially identical to first pipe, is shortened by cutting off the portion of the open end. Now, as both pipes vibrate at their fundamental frequencies, the beat frequency of 11.6 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 343 m/s.
