Question

a circular disc of mass M and radius R is in pure rolling on horizontal surface as shown. the velocity of its centre of mass is Vo. then the ration of net velocity of point a and point b will be??​

Answer 1

Answer:

hope it helps..

Explanation:

ω=Rv (rolling)

Angular momentum about origin =mvr⊥+Ioω

v⊥= distance perpendicular to velocity from origin

Io= Moment of inertia about point O (centre of mass of disk)

=m1ωR×R+2mR2ω

⇒23mR2ω (ω=∞)

=23mR2∞.
