Answer:
4.2rad/s
Explanation:
momentum is the product of the mass of a body and its velocity
conservation of angular momentum
total momentum before collision =total momentum after collision
L1=L2
initial momentum
L1=r*p=Rmu
final angular momentum
L1=I*ω=
(mR^2+0.5mR^2)ω
Angular momentum equals
Rmu=(mR^2+0.5MR^2)ω
to solve for ω
[tex]\frac{Rmu}{mR^2+0.5MR^2}[/tex]
[tex]\frac{0.2*0.1*5}{0.1*0.2^2+0.5*1*0.2^2}[/tex]
ω=4.2rad/s (Approximately)
ω= angular velocity after the collision
