# Ah, solving a prob with two unknown values

:uhh: The problem gave me the final velocity which is 460m/s and that gravity is 10m/s^2 (initial v = 0 when the object goes straight up.). The problem asks for the highest point and how high it will be... So far I've goten vf = 460m/s, vi = 0, and A = 10m/s^2. Hmmm so how do I apply the big five formulas to this problem?

Thanks.

$$Use\ v^2=u^2+2as$$
