JEE Main 8 April 2026, Shift 2, Physics Q32

Question 32 of 75 in this shift, Physics question 7 of 25, Section A.

A solid cylinder having radius RR and length LL is slipping on a rough horizontal plane. At time t=0t = 0 the cylinder has a translational velocity v0=49v_0 = 49 m/s, perpendicular to its axis and a rotational velocity v0/4Rv_0/4R about the centre. The time taken by the cylinder to start rolling is ________ seconds. (coefficient of kinetic friction μK=0.25\mu_K = 0.25 and g=9.8g = 9.8 m/s2^2)
