1. The problem statement, all variables and given/known data The problem says the general formula for the height (h) after (t)seconds of a projectile launched upward from ground level with initial speed (v) is h = vt-1/2gt^2, where (g) is the gravitational constant (appox. 32m/s^2). Show That the greatest height of the projectile is v^2/2g 2. Relevant equations 3. The attempt at a solution I tried alot a stuff .... I think The problem I am having here is making a relation between the gravitional constant and the given equation. Thanks guys.
