1) Do #5 in the Thought Questions section in Chapter 2.
2) Do # 13 in the Problem section in Chapter 2.
3) What would be the period of an object in circular orbit at a distance of 1000 km above the surface of the Sun? What would its orbital velocity be in meters/sec?
4) Do #7 in the Thought Questions in Chapter 3.
5) If you are traveling in a car which decelerates from 60 miles/hour to 0 miles/hour in a distance of 20 feet (crash), what force will you feel? Assume that you are decelerated at a constant rate. How much would you weigh if you measured your weight in the direction of deceleration?
Hint: Distance = (acceleration) (time)2
6) Calculate the gravitational force between a 70 kg person and a 3 kg baby sitting 1 meters away. Compare this to the gravitational force between the baby and the planet Jupiter. Assume that Jupiter is located at closest approach to the Earth.
