Physics - Circular Motion Question with Solution | TestHub

A block of mass $\mathrm{m}=20\mathrm{kg}$ is kept at a distance $\mathrm{R}=1\mathrm{m}$ from central axis of rotation of a round turn table (A table whose surface can rotate about central axis). Table starts from rest and rotates with constant angular acceleration, $\alpha =3\mathrm{rad}/{\sec }^2$. The friction coefficient between block and table is $\mu =0.5$. At time $\mathrm{t}=\frac{\mathrm{X}}{3}$ sec from starting of motion (i.e. $\mathrm{t}=0\sec$ ) the block is just about to slip. Find the value of x.
