Where in the world could I use this? If friction is ignored, the velocity v (in feet per second) of a roller coaster when it reaches the bottom of a hill, can be found using the formula , where h is the height (in feet) of the hill. The approximate velocity of one of the fastest roller coasters in the world is 176 ft/sec. Find the height of the hill.
