Hello guys, good morning. :)(adsbygoogle = window.adsbygoogle || []).push({});

I need your help regarding Circular Motion. I'm hoping that someone will help me heartily with this.

These are the following problems:

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. Determine the speed of the satellite orbiting at a height of 700km above the Earth's surface.

mass of earth = 5.98 x 10^24kg

radius of earth = 6.38 x 10^6m

3. How much centripetal acceleration is produced when the object rotates 40 times a second with 4.89m radius? Also compute for the tangential velocity.

That's all guys. Hope you can help me with these. Thanks advance.
