Question

The paths of two small satellites, X and Y, of equal mass of 4.00 kg each, are shown below. They orbit around a massive star, as illustrated, with M = 3.20×1029 kg. The orbits are in the plane of the paper and are drawn to scale.

In the statements below KE is kinetic energy, PE is potential energy, and |L| is magnitude of the angular momentum.

1.The speed of X at m is .... that at c

2.At m, the KE of X is .... that of Y.

3.The |L| of X at a is .... that at w.

4.The PE of Y at p is .... the PE of X at c.

5.At m, the PE of X is .... that of Y.
