- Homework Statement
- You fire a ball with an initial speed at an angle Φ above the surface of an incline, which is itself inclined at an angle θ above the horizontal (see the above image). (a) Find the distance measured along the incline, from the launch point to the point when the ball strikes the incline. (b) What angle Φ gives the maximum range, measured along the incline? Ignore air resistance.

- Relevant Equations
- I tried to do this one using

x = y / tan(phi + thetha)

y = v_0sin(phi + theta)t - (gt^2) / 2

x = v_0cos(phi+theta)t => t = x / (v_0cos(phi+theta))

But it seems to get too complex and am not sure whether it is correct.. my solution got a bit messy + incorrect

Thanks in advance!
