Question
A uniform thin cylindrical disk of mass M and radius Ris attached to two identical massless springs of springconstant k which are fixed to the wall as shown in thefigure. The springs are attached to the axle of the disksymmetrically on either side at a distance d from itscentre. The axle is massless and both the springs andthe axle are in a horizontal plane. The unstretched lengthof each spring is L. The disk is initially at its equilibriunmposition with its centre of mass (CM) at a distancefrom the wall. The disk rolls without slipping with velocityVo Voi . The coefficient of friction is u. \lbrack IT-JEE 2008\rbrack
