Question 187536: a sandbag falls out of a hot air balloon that is 144ft above the ground. How long does it take for the sandbag to reach the ground?
to find the answer, use the equation 0=-16t^2+144 in which the time(t), in seconds, is the time it takes to hit the ground.
need to know the second(s)

a sandbag falls out of a hot air balloon that is 144ft above the ground. How long does it take for the sandbag to reach the ground?
to find the answer, use the equation 0=-16t^2+144 in which the time(t), in seconds, is the time it takes to hit the ground.
---------------
use the equation 0=-16t^2+144
16t^2 = 144
t^2 = 9
t = 3 seconds (ignore the t = -3)
