Suppose an object is dropped from a height h0 above the ground. Then its height after t seconds is given by h = −16t 2 + h0, where h is measured in feet. Use this information to solve the problem.

Question

A ball is dropped from the top of a building 59 ft tall. (Round your answers to three decimal places.)
(a) How long will it take to fall half the distance to ground level?
t = sec

(b) How long will it take to fall to ground level?
t = sec

Answer 1

ho=59
h=0

0=-16t^2+59
t= 1/4 sqrt (59)
