1. In the fastest measured tennis serve,the ball left the racquet at 73.14 m/s. A served tennis ball is typicallyin contact with the racquet for 30.0 ms and starts from rest.Assume constantacceleration. (a) What was the ball’s accelerationduring this serve? (b) How far did the ball travel during the serve?
2. In an experiment, a shearwater (a seabird) was taken fromits nest, flown 5150 km away, and released. The bird found its wayback to its nest 13.5 days after release. If we place the origin at thenest and extend the +x-axis to the release point, what was thebird’s average velocity in m/s (a) for the return flight and (b) forthe whole episode, from leaving the nest to returning?
