Projectile Motion, With out numbers :( 1. The problem statement, all variables and given/known data A body is projected at an angle such that the horizontal range is equal to three times the greatest height. find the angle of projection. 2. Relevant equations I dont know 3. The attempt at a solution all i got so far is that vx= v cos(angle) and vy= v sin(angle) This is a really tricky question for me and i do not know where to start.
