Homework Statement:
1: Under what conditions will a 0.030-kg marble-Earth system and a 3.00-kg rock-Earth system have the same gravitational potential energy? Do not use the case where both objects are at the reference level.

2: Under what conditions will a moving 0.030-kg marble and a moving 3.00-kg rock have the same translational kinetic energy? Do not use the case where both objects are stationary.
Relevant Equations:

You must make your best attempt at solving these problems. See the homework guidelines:

However, if you really have no idea, then you should study the relevant course material before attempting the problems.
