1. The problem statement, all variables and given/known data A ball rolls off a table at speed v and impacts the floor at distance d. What is the angle between the path of the ball and a vertical line drawn at the moment of impact. 2. Relevant equations I have derived from basic projectile motion formulae: Time of impact t = sqrt(2h/g) Distance d = Vox * sqrt(2h/g) Velcocity at impact = sqrt(Vox^2 - gt^2) 3. The attempt at a solution I don't really know where to start, I believe I have all the required information above but how do I apply it ?
