1 One end of a light inextensible string of length 0.8m is attached to a particle P of mass mkg. The other end of the string is attached to a fixed point O. Initially P hangs in equilibrium vertically below O. It is then projected horizontally with a speed of 5.3ms -1 so that it moves in a vertical circular path with centre O (see diagram). 5.3ms −1 At a certain instant, P first reaches the point where the string makes an angle of 1 r radians with the downward vertical through O. (...
