Unit 4: Energy
Potential Energy, Kinetic Energy, Total Mechanical Energy
h=120m
n=0m
The image above shows a kid sledding down a hill that is 120 m tall. The mass of the kid is
m40kg, he is traveling at 15m/s down the hill. Once he reaches the bottom of the hill he is at a
height of 0 m and is STOPPED. (g = 9.8 m/s²)
1. Is there potential energy present in the image above? Explain.
