Homework Help: Physics

Posted by Anonymous on Friday, April 27, 2012 at 10:45am.

A pendulum consist of a particle P of mass m, attached to one end of a model string of length l=2.85m. The other end of the string is attached to a fixed point O and the particle moves in a vertical circle about the fixed point.

The angle made by the string with the vertical is measured anticlockwise and we assume that the only forces acting on the particle are its weight W and the tension force T due the string. The particle starts at the lowest point with an initial horizontal velocity of sqrt(7gl/2) in the clockwise direction.

Calculate the speed of the particle, in m/s when the tension becomes zero.
