Question

Help please?
Once the rocket is launched, its height in feet, h(t), can be found using the height function

h(t) = -16t² + 96t where t represents time in seconds. Find the time when the rocket finally hits the ground.

My work: 0=-16t^2+96t = -16t(t-6)=0 = -16t=0 , t=0 and t-6= t=6

Answer 1

yes thats correct
t=0 corresponds to time fired
t = 6 to the time it returns to ground

Answer 2

Thank you so much!
