If a projectile is shot at an angle of #(5pi)/12# and at a velocity of #15 m/s#, when will it reach its maximum height??
Split the velocity up into x-components and y-components:
We only care about the y-component in this case since we want to know maximum height. The initial velocity is
The equation in the top right corner has all four of those components. Plug into that equation:
Solve for d:
