Find the speed of a satellite orbiting at that height

Reference no: EM13719410

Solve the following problem:

Problem I: At what height above the earth is the free-fall acceleration 25 % of its value at the surface? Assume Rearth = 6.37 × 10⁶ m.

Problem II: What is the speed of a satellite orbiting at that height? Assume Mearth = 5.98 × 10²⁴ kg.

Can someone please explain what the heck is going on above problem?
