Homework Statement
A rocket is shot with velocity smaller than the escape velocity. at what angle to the horizon should it be fired in order to reach maximum height.
Homework Equations
Total energy: ##E=\frac{1}{2}mv^2-\frac{GMm}{r}##
The Attempt at a Solution
The equation isn't vectorial, it doesn't say anything about direction, so, i guess in any direction you shoot it it will reach the same height, but the answer is 900
