Rotational MotionHard
Question
A disc of radius R = 2m moves as shown in the figure, with a velocity of translation of 6v0 of its centre of mass and an angular velocity of 
. The distance (in m) of instantaneous axis of rotation from its centre of mass is
. The distance (in m) of instantaneous axis of rotation from its centre of mass isOptions
A.3
B.4
C.5
D.6
Solution
Instantaneous axis of rotation lies above the centre of mass where v - ωr = 0 ⇒ r = 
= 3R
