Asked by Robert
A helicopter drops a box of supplies after a disaster. The function represents the height y (in feet) of the box t seconds after it is dropped. After how many seconds does the box hit the ground?
y=100-16t^2
y=100-16t^2

Your equation suggests that the box was dropped from a height of 100 ft
solve :
0 = 100-16t^2
16t^2 = 100
take square root of both sides
4t = 10
take over.

0 = 100-16t^2
