A particle is suspended from a point A by an inextensible string of length L. It is projected from B with a velocity V, perpendicular to AB, which is just sufficient for it to reach C. (a) Show that, if the string is just to be taut when the particle reaches C, its speed there is (gL). A (b) Find the speed V with which the particle should be projected from B. (c) At which point of the circular path is the string most likely to break? B
