Young's modulus question...
A sphere of radius 10 cm and mass 25 kg is attached to the lower ends of a steel wire which is suspended from the ceiling of a room. the point of the support is 521 cm above the floor. When the sphere is set swinging as a simple pendulum, its lowest point just grazes the floor. Calculate the velocity of the ball at its lowest point.
I think some information is missing here...Either th strain or the initial length or change in length should be given so that i can calculate tension and hence equate it to mv2/r + mg...
