A rocket is shot straight up with an initial speed at 500 m/s.
The equations the teacher went over beforehand were
Yf = 1/2 A(T)^2 + Vi(T) + Yi
Vf = A(T) + Vi
The Attempt at a Solution
So far I have
Vf = (-9.8)(T) + 500 m/s
Yf = 4.9T2 + 500T + 0
...and I have no idea how to go about solving for the rest of the unknown variables. It seems like I need T somehow, but I don't know how I can get it from the information given.
