Suppose an object is dropped from a height h₀ above the ground. Then its height after t seconds is given by

h = 16t² + h₀,

where h is measured in feet. Use this information to solve the problem. A ball is dropped from the top of a building 82 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 grou
