A horizontal plank having mass m lies on a smooth horizontal surface. A sphere of same mass and radius r is spined to angular frequency omega_(0) and gently placed on the plank as shown in the figure. If coefficient of friction between the plank and the sphere is mu . Find the distance moved by the plank till sphere starts pure rolling on the plank. the plank is long enough.

A plank of mass M is placed on a smooth hroizonal surface. Two light identical springs each of stiffness k are rigidly connected to structs at the ends of the plank as shown. When the spring are in their unextended position the distance between their free ends is 3l . a block of mass m is placed on the plank and pressed aganist one of the springs so that it is compressed by l . To keep the blocks at rest it is connected to the strut by means of a light string, initially the syetem is at rest. Now the string is burnt. Maximum displacement of plank is:
