13Conservation of energy solves d problem in single step...!!!
any prob...?
24Here mechanical energy is conserved. No work is done when the string hits the pin and partially wraps around it,because the part of the string that experiences a force is the part that is in contact with the pin, and is stationary.
initially and at max heiht velocity =0 => KE=0..........
