A thin spherical shell m R translates without any rotation upon rough horizontal surface with centre m with velocity Vo friction appears which retards translational motion but causes the body to rotate At t the rigid body rolls without slipping 71 The distance covered by the shell from t 0 to t to 2 2 8 Vo 1 25 4 9 2 4 v 3 54 9 72 Work done by force of friction from t 0 to t to s 2 1 3 4 5 mv 4 25 t 0 mv 2 4 4 v 25 9 2 8 v 5 9 mv 2 5 t to 2 4 mv E 73 A solid cylindrical disc rolls down on inclined plane having inclination 60 with horizontal withou The initial acceleration of the topmost point of the disc is
