Answer:
The firework will take 5 s to reach the ground again.
Step-by-step explanation:
For the firework to reach the ground it's height must be equal to 0, so we need to solve the given equation for t with h=0. We have:
h = -16t² + 80t
0 = -16t² + 80t
16t² -80t = 0
t(16t - 80) = 0
In this case we have an incomplete second order equation, there are only two values that can satisfy that equality, these are given bellow:
t = 0 s
16t - 80 = 0
16t = 80
t = 80/16 = 5 s
Since 0 s is when it was launched, then 5 s is the time it takes to reach the ground again.
