Question

The function d=16t^2 models the distance d, in feet, that an object falls in t seconds. Find the inverse function and use the inverse function to estimate the time it takes an object to fall 100 feet.

Answer 1

Explanation:

d = 16t^2

t^2 = d/16

t = 0.25√d

When d = 100 ft, t = 2.5 seconds
