Solve the following problems given below:
Problem I: At what height above the earth is the free-fall acceleration 20 % of its value at the surface? Assume Rearth = 6.37 x 106 m.
Problem II: What is the speed of a satellite orbiting at that height? Assume Mearth = 5.98 × 1024 kg.
Please help for the above problems, completely confused!! Show each steps if possible, Thanks.
