I was given the situation, A rocket, initially at rest on the ground, accelerates straight upward from rest with constant net acceleration a , until time t1, when the fuel is exhausted.(adsbygoogle = window.adsbygoogle || []).push({});

Find the maximum height H that the rocket reaches (neglecting air resistance).

Express the maximum height in terms of a, t1, and/or g . Note that in this problem, g is a positive number equal to the magnitude of the acceleration due to gravity.

I found the equation to be (1/2)a((t_1)^2)*(1+(a/g)) This formulaa is correct. I am having trouble finding the max. height that the rocket will reach. height when the net acceleration is a=3g for t1=5.00s and use g=9.81m/s^2. I tried plugging in a=3g into the equation and got and incorrect answer so i tried 2g, taking g away from the aceleration becuase of gravity downword and as well got it wrong. Im not sure what i am doing wrong
