Q:
# Entertainment For a scene in a movie, a sack of money is dropped from the roof of a 600-foot skyscraper. The height of the sack above the ground in feet is given by h = -16t2 + 600, where t is the time in seconds. How long will it take the sack to reach the ground? Round to the nearest tenth of a second.

Accepted Solution

A:

Answer:6.1 s Step-by-step explanation:h = -16t² + 600
When the sack reaches the ground, h = 0.
0 = -16t² + 600
16t² = 600
t² = 600/16
t² = 37.5
t = 6.1 s
It will take 6.1 s for the sack to reach the ground.
