Question

Asteroids X, Y, and Z have equal mass of 6.0 kg each. They orbit around a planet with M=3.20E+24 kg. The orbits are in the plane of the paper and are drawn to scale.

In the statements below, TE is the total mechanical energy, KE is the kinetic energy, and PE is the potential energy.

The PE of Z at s is .... the PE of X at r
The PE of Z at m is .... the PE of Y at r
The PE of Y at c is .... that at m
The TE of Y is .... the TE of X
The KE of X at r is .... that at s
The TE of Y is .... the TE of Z
The PE of Z at s is .... the PE of X at s
The speed of Z at m is .... that at i
