Question
1. Joe Physics is travelling on a jet airliner. As it accelerates down the runway, he holds a pendulum (consisting of a small washer on the end of a thread) in front of him and observes that the pendulum is displaced 10.0° from its usual vertical alignment. Help him by calculating the acceleration of the aircraft.2. A 5.00 g bullet is fired into a 6.00 kg block, which is suspended from a string 1.00 m long. The string deflects through an angle of 12.0°. How fast was the bullet moving? 3. A large superball and a small superball are dropped from the same initial height H. Both balls bounce back up to a height h , which is just a bit less than H. If, however, the small superball is placed immediately above the large superball and both are dropped to the ground simultaneously from height H, the small superball rebounds to a height h' >>> H! Explain this in terms of the Conservation Laws discussed in this chapter.

Explanation / Answer
1. Joe Physics is travelling on a jet airliner. As it accelerates down the runway, he holds a pendulum (consisting of a small washer on the end of a thread) in front of him and observes that the pendulum is displaced 10.0° from its usual vertical alignment. Help him by calculating the acceleration of the aircraft. tension = T Tsin(10) = ma Tcos(10) = mg so tan(10) = a/g a = gtan(10) = 1.73 m/s^2
