The arrangement shows a solid cylinder of radius R placed between two planks. There is no slipping at rough surfaces. The planks are given a horizontal constant velocity as shown. The angular velocity of the cylinder is:
Options:
Answer:
D
Solution:
No slip gives bottom contact velocity -V and top contact velocity 4V.
Solving Vcm-ωR=-V and Vcm+ωR=4V gives ω=5V/(2R).
