A roller coaster starts from the top of a hill at rest with a potential energy of 3300 J.

What is the total mechanical energy of the roller coaster?
How much work was needed to bring the roller coaster to the top of the hill?

If the roller coaster begins to fall and now has a potential energy of 1120 J, and no work was done, how much kinetic energy does it now have?
