Answer :

a) As from the question the disc is rotating about its horizontal axis before coming in contact.


Hence it’s


b) Linear velocity of point at rim decreases due to force of friction.


c) Linear speed of centre of mas of disc increases due to acceleration gained by it due to friction.


d) Friction is responsible for effects in b and C.


e) Rolling starts when


where ω is angular speed of disc.


f) Acceleration produced in centre of mass due to friction



Angular acceleration produced by torque due to friction



As we know that




For rolling without slipping
