Question 12

Solve
The distance, s(t), in feet traveled by a freely falling object is given by the function s(t) = 162, where
t is time in seconds. Use this formula to find the time it would take for an object to fall to the
ground from a cliff that is 1024 feet high.

Answer 1

8 seconds

Explanation:

The correct formula is

s(t) = 16t²

-------------------------

1024 = 16t²

Divide both sides by 16

64 = t^2

Take the square root of both sides

8 = t
