What is the gravitational potential energy of the system

Reference no: EM13675343

A 50.0-kg shell is shot from cannon at Earth’s surface to a height of 425 m. The system is the shell plus Earth, and the reference level is Earth’s surface.

1. What is the change in the potential energy when the shell falls to a height of 225 m?

2. What is the gravitational potential energy of the system when the shell is at this height?
