A block of mass
m=20 kg is kept at a distance
R=1m from the central axis of rotation of a round turn table (a table whose surface can rotate about the central axis). Table starts from rest and rotates with constant angular acceleration,
α=3 rad/sec2. The friction coefficient between the block and the table is
μ=0.5. At time
t=x30 from the starting of the motion (i.e.
t=0), the block is just about to slip. The value of
x is
(
g=10ms−2)
