A toy cannon is placed on a ramp that has a slope of angle alpha = Pi/8. The

cannonball is projected up the hill at an angle of pheta above the horizontal (see

figure) and has a muzzle speed of v0 = 4.2 m sā1.

(a) Given pheta = Pi/5, compute R, the range of the cannonball, as measured

along the ramp.

(b) What angle do you have to choose to ensure that the cannonball flies

horizontally when hitting the ramp?

(c) What angle do you have to choose to obtain maximal range R?

2. Relevant equations

3. The attempt at a solution

The only way i can think to calculate this is by considering the slope of the hill to be the ground level and then correcting gravity by splitting it into gcos(pi/8) and gsin(pi/8)

would this approach yield the correct results?
