[SOLVED] Projectile Motion - Ramp Angle Good evening everyone! 1. The problem statement, all variables and given/known data This is a classic ramp angle question. I am trying to find the angle of a ramp in order for a bus to complete the gap (Yes, this is from the film Speed, and I have searched, but haven't found a solution.) Known: Velocity = 31.29 m/s Distance of gap = 15.24 m The landing part of the road is level with the take off. 2. Relevant equations θ = (1/2) sin^-1 (fg x d / v2). 3. The attempt at a solution θ = (1/2) sin-1 (9.81 x 15.24 /31.292) θ = (1/2) sin-1 (149.5044 / 979.0641) θ = (1/2) sin-1 (0.1527) θ = (1/2) (8.7834) θ = 4.3917 degrees. This answer does not quite seem right. I have gone through my calculations, but I cannot find an error. Perhaps my equation is wrong, I am not sure.
