1. When the radius and mass are held constant, what do you expect to happen to the centripetal force if the frequency of rotation is increased?
2. What will happen if a rotating platform was set up slightly off the horizontal? Would anything change? What in particular?
3. A ball rotates in a horizontal circle at a constant speed of 10m/s. what are the tensions in the upper and lower strings? The mass of the ball is 3kg.

4. What angle of bank is necessary for a car to make it around a 130m curve at a speed of 60kph without relying on friction.
5. Determine the speed of the satellite orbiting at a height of 700km above the Earth's surface.
mass of Earth = 5.98 x 10^24 kg
radius of Earth = 6.38 x 10^6 m
~~~~~~~~~~~~~~~~~~~~~~~~
I would greatly appreciate the help...
Oh, and btw, I also need Free Body Diagrams for problems 3 - 5 (so that i won't get confused
)
Thanks again...
