A. If a roller coaster has a total of 6632 Joules of energy at the top of a hill, then at the bottom of the hill how much total energy will it have. (assume: no brakes, no motor, no air resistance, no external forces) B. If a roller coaster begins at rest at the top of a 11 meter hill, then at the bottom of the hill how fast will it be going? C. If a roller coaster begins at rest at the top of a hill, and at the bottom of the hill is moving at 25 m/s, how tall was the hill?
help solve 5 part question please. Thank you :)
