Review of Work

Two balls near the Earth:

• Calculate the work done in moving each ball from y = 0 meters to y = 5 meters
• Calculate the work per kg for moving each ball from y = 0 m to 5 m
• Calculate the change in gravitational potential energy per kg for moving each ball from = 0 m to 5 m
• Calculate the speed each ball would have as it reached the ground if released from 5 meters above the ground
