what would be the speed of the roller coaster at the bottom of the drop?
A new ride being built at an amusement park includes a vertical drop of 71.6 meters. Starting from rest, the ride vertically drops that distance before the track curves forward. If friction is neglected, what would be the speed of the roller coaster at the bottom of the drop?

d = (1/2)gt^2
71.6 = (1/2)(9.81)t^2
t^2 = 14.6
t = 3.82
v = at = (9.81)(3.82) = about 37.5 m/s
