Question

A rock falls from a tower that is 352 feet high. As it is falling, it given by the formula h=352-16t/2. How many seconds (in tenths) will it take for the rock to hit the ground (h=0)?

Answer 1

Below

Explanation:

0 = 352-16t/2 <======are you sure of this equation? (it is incorrect)

-352 = -16t/2

704 = 16t

t = 44 s

The correct equation is

0 = 352-16t^2

which results in t = 4.7 seconds
