Question
Initial angular velocity of a circular disc of mass M is ω1. Then two small spheres of mass m are attached gently to diametrically opposite points on the edge of the disc. What is the final angular velocity of the disc?
Options
A.
B.
C.
D.
Solution
Angular momentum = conserved
MR2ω1 = 2mR2ω MR2ω ⇒ ω = 
MR2ω1 = 2mR2ω MR2ω ⇒ ω = Create a free account to view solution
