What is the height of the coaster when the velocity is 90 ft/sec? Show all work using the equation editor and label your final solution. Round your final answer to the nearest hundredth, but remember you should NOT round in the middle of the question. Write a sentence explaining your answer.
Hard to say from your description.
But if something came down from height h
and had no loss of energy due to friction or whatever then the kinetic energy is equal to the potential energy at the start
(1/2) m v^2 = m g h
or
v = sqrt (2 g h)
= sqrt ( 64 h) in the ancient foot type units
90 = sqrt (64 h)
64 h = 8100
h = 8100/64 feet
