Problem
I. A 1.2 meter long steel bar with a mass of 10 kg is held at in the center {as in the class demonstration). It is struck from the top end setting up a standing wave in the bar such that it rings.
1. What is the lowest frequency at which it will resonate for more than a few seconds?
2. Sketch the standing wave.
3. In less than 10 words: Characterize the wave that is oscillating in the steel bar?
II. Jupiter is T?8,54T,200 km from the sun, has a mass of 1.9 x 1027 kg and orbits the sun once every 12 years. The sun is 1000 times the mass of Jupiter. Use scienti?c notation.
1. What is the angular velocity of Jupiter in its orbit?
2. What is the angular acceleration of Jupiter in its orbit?
3. What is the centripetal acceleration of Jupiter in its orbit?
4. What is the centripetal force on Jupiter in its orbit?
5. What is the tangential velocity of Jupiter in its orbit?
6. What is the tangential acceleration of Jupiter in its orbit?
