- Solution: The projectile motion equations: x = x₁ + (vo cos 0) t y = yo + (vo sin 0o) t - 1/2gt² Call the starting point (xo, yo) = (0,0). To find (x, y) for the ending point, use triangle trig on the hill angled at 20°: x = d cos 20° = .940d and y = d sin 20° = .342d Plug in: .940d = (vo coso) t (Eqn. 1) .342d = (vo sin 0o) tgt² (Eqn. 2) The variable t is not mentioned in the problem.
