Inverses and Radical Functions · Exercise 67

Determine the function described and then use it to answer the question.

An object dropped from a height of 600 feet has a height, $h (t),$ in feet after $t$ seconds have elapsed, such that $h (t) = 600 - 16 t^{2} .$ Express $t$ as a function of height $h,$ and find the time to reach a height of 400 feet.
