19. The velocity v in feet per second of a roller coaster at the bottom of a hill is related to the vertical drop h in feet and the velocity vo in feet per second of the coaster at the top of the hill by the formula vo = √v² - 64h. If the coaster has a velocity of 7 feet per second at the top of a 50-foot hill, what is the velocity at the bottom of the hill?
