(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A cannon ball is fired with speed v0 at an angle phi above the horizontal. The launch point is at height h above the ground. Find the time to hit the ground, and the magnitude of the velocity when the ball hits the ground (in terms of v0, g, h, [tex]\phi[/tex])

2. Relevant equations

y=v0sin([tex]\phi[/tex])t - 1/2gt^2

vy=v0sin([tex]\phi[/tex]) - gt

3. The attempt at a solution

how do i account for initial height?
