1. The problem statement, all variables and given/known data An object which has mass = m is released from point A which has height of h. The object moves along the rail with no friction. The rail OB is a semicircular rail which C is the center and R is the radius. If the object falls from the rail at the point B, find the following. 1) h/R 2) Distance of the object from point O if the object lands on the surface without hitting the rail 2. Relevant equations 3. The attempt at a solution Using the law of energy conservation mgh + 1/2mv2 = mgh + 1/2mv2 The object should have velocity of sqrt(2gh) at point O What should I do next at the semicircular rail? How to calculate the reaction from the rail since the object will fall if the reaction is 0?
