1. The problem statement, all variables and given/known data A rocket is shot straight up with an initial speed at 500 m/s. 2. Relevant equations The equations the teacher went over beforehand were Yf = 1/2 A(T)^2 + Vi(T) + Yi Vf = A(T) + Vi 3. 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.
