Compute all parts of given problem:
Problem: A 123-kg care package with a parachute is dropped from an airplane and reaches a terminal speed of 5.00 m/s,
Part I: What is the rate of its potential energy change?
Part II: What is the rate of work done by the air resistance?
Please explain all work and steps to determine the rate of work done by the air resistance.
