Question

An 76 kg satellite orbits a distant planet with a radius of 4500 km and a period of 280 min. From the radius and period, you calculate the satellite's acceleration to be 0.63 m/s2. What is the gravitational force on the satellite?

Answer 1

gravity is the centripetal force keeping the satellite in orbit

g = m a = 76 kg * .63 m/s^2
