find the velocities of the particles m1 and m2 just after the string is taut. the particle m1 moves with velocity v0 when the string is not taut. Neglecting fricting in all contacting surface Two particles of masses m1 and m2 are connected by a light and inextensible string which passes over a fixed pulley. Initially
