Rotational Motion Question 201
Question: A cylinder A rolls without slipping on a plank B. The velocities of center of the cylinder and that of the plank are 4m/s and 2m/s respectively in same direction, with respect to the ground. Find the angular velocity of the cylinder (in rad/s) if its radius is 1m.
Options:
A) 2rad/sec
B) 4rad/sec
C) 6rad/sec
D) l0rad/sec
Show Answer
Answer:
Correct Answer: A
Solution:
[a] For rolling, $v _{A}=2m/s$
or $4-1.\omega =2$
or $\omega =2rad/\sec $(clockwise)
