1. Earth's moon is about 3.8 x 108 m away from Earth and takes about 28 days to go around the Earth that has a mass of 5.97 x 1024 Kg. Jupiter's moon, 10, is about the same sin as our moon, is about 4.2 x 108 m away from Jupiter but takes only 1.8 days to travel around Jupiter that has a mass of 1.898 x 10^27 Kg. 
a. What type of force does each moon experience (centripetal or centrifugal)? 
b. What provides this force? 
c. Derive an equation that shows what factors determine the velocity of each moon so you can explain why Jupiter's moon is so much faster. Start with a force diagram. 

2. You are designing a spinning spaceship for long distance space travel. If the radius of your station is 12 m, how fast does a person standing at the outer edge of the station have to travel so that they feel like they are on Earth? 

3. For the situation of a banked road, draw a force diagram for a car coming toward you as it is turning. Identify all of the forces and components of forces that contribute to the force needed to make the turn. Then assume there is no friction and derive and equation for the maximum velocity a car can go around a curve when the radius of the curve is R and the banking angle is 6. Your equation must be in terms of given quantities and known constants. 

Answer all or both, I just need some help here. yes it's obviously homework.
