A disc rotating about its axis with angular speed `ω_(o)` is placed lightly (without any translational push) on a perfectly frictionless table. The radius of the disc is R. What are the linear velocities of the points A, B and C on the disc shown in Fig. 7.41? Will the disc roll in the direction indicated ?

Text Solution

Verified by Experts

Velocity of `A=omega_(0)R`, which is in the same direction as the arrow.
b) Velocity of `B=omega_(0)R`, which is in a direction opposite to the arrow
c) Velocity of `C=omega_(0)R//2` which is the direction of the arrow.
d) The disc will not roll in the direction indicated as the table is perfectly frictionless and without friction a body cannot roll.
