Question

A small package of weight W is projected into a vertical loop at A with a velocity V_0. The package travels without friction along a circle of radius r and is deposited on a horizontal surface at C. For each of the two loops shown, determine (a) the smallest velocity V_0 for which the package will reach the horizontal surface at C. (b)the corresponding force exerted by the loop on the package as it passes point B
