Mr. Kangas is sky-diving. The plane he is riding in is 3,000 m in the air and he has a mass of 90 kg. Construct an LOL diagram for when Mr. Kangas is...

1. Standing in the plane
2. Falling through the air

*Note, we can ignore the horizontal velocity of both Mr. Kangas and the plane in the context of this problem, since it does not change while Mr. Kangas is on the plane or in free fall.

1. Write a total energy equation for scenario 4 and scenario 5.

Standing in the plane	Falling through the air
Total Energy =	Total Energy =

1. Calculate the gravitational potential energy of Mr. Kangas while in the plane.

1. How much gravitational potential energy remains once Mr. Kangas is falling with 1,000,000 J of kinetic energy?

Use your Total Energy Equations.

1. At what height above the ground is Mr. Kangas at this point?
