235 kg roller coaster is at the top of a hill with a velocity of 5.60 m/s from a height of 100.0 m above the ground. A) Determine the velocity of the roller coaster at a height of 40.0 m further down the track, neglecting friction. B) What reference point did you choose as zero height? Show how you could come up with the same answer to A if you chose another reference point for height.
