Find the kinetic energy k of a satellite with mass m in a circular orbit with radius r. express your answer in terms of m, m, g, and r.

Explanation:

The kinetic energy is defined as:

Here, m is the object's mass and v its speed. In this case the speed of the satellite is the orbital speed, which is given by:

Here, G is the gravitational constant, M is the mass of the object that the satellite is orbiting and R is the radius of its circular orbit. Replacing (2) in (1):

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
