My teacher gave me a studyguide for the next exam with the answers. I need help figuring out how to do these problems:
1.) What is the centripetal acceleration of a 1000 kg car rounding a curve with a radius of 200 m at a speed of 25 m/s? The answer is 3.13 m/s^2
2.) What Power is required to raise an 1100 lb elevator at a speed of 10 ft/s?
3.) What is the gravitational pull exerted by the eart on a 200 kg satellite which is orbiting the earth at an altitude of 6400 km?
Thanks in advance!
