Homework Statement
Prove that a projectile launched on level ground reaches maximum height midway along its trajectory.
The Attempt at a Solution
Is the attached solution the correct way to prove?
I tried another method which was:
t = 0 or t = 2vyi/g
[y(2vyi/g) = y(0) + vi.t -0.5gt^2]/2 [itex]\equiv y(vyi/g) = y(0) + vyi.t -0.5gt^2 = vyi^2/g[/itex]
then solve but it couldn't be solve.
This was so that I could prove that the total displacement in t_apex = vyi/g is equivalent to half the displacement achieved in y(2vyi/g) = y(0) + vi.t -0.5gt^2
