A solid cylinder having radius R and length L is slipping on a rough horizontal plane. At time t = 0 the cylinder has a translational velocity v0=49m∕s, perpendicular to its axis and a rotational velocity v0∕4R about the centre. The time taken by the cylinder to start rolling is ________ seconds. (coefficient of kinetic friction µk=0.25 = 0.25 and g=9.8m∕s2)
