Question

A man at the top of a building that is 75 feet tall drops a ball. The distance from the ball to the ground can be modeled by the equation h = -16t2 + s, where h is the height from the ground, t is the time in seconds, and s is the initial height from the ground in feet. How long will it take for the ball to reach the ground? Round your answer to the nearest tenth of a second.

Answer 1

For ball a

u=0

g=10m/s

2

d=(100−x
