A satellite is placed in a circular orbit 160 km above the Earth’s surface. Determine constant orbital speed?

A satellite is placed in a circular orbit 160 km above the Earth’s surface. Determine the (constant) orbital speed v and the time t required for one complete revolution of the satellite. You can assume that the effect of gravity at this height of 160 km is the same as at the Earth’s surface (i.e., g = 10 m/s^2).... show more A satellite is placed in a circular orbit 160 km above the Earth’s surface.
