1. The problem statement, all variables and given/known data " An airplane turns slowly for 9.2s horizontally. The final velocity of the plane is 360km/hr [N]; the average acceleration during the turn is 5.0m/s^2 [W]. What is the initial velocity of the plane?" 2. Relevant equations a=ΔV/t 3. The attempt at a solution at=Δv (5.0m/s^2[W])(9.2s)=Δv 46m/s[W]=Δv ...then from here I get stuck. I know the horizontal component of the plane at the end (final) is 0 and the vertical component (final) is 360km/hr, but this doesn't help me find any obvious solution.
