Answer:
0.2932 rad/s
Explanation:
r = Radius = 2 m
 = Initial angular momentum =
 = Initial angular momentum = 
 = Initial angular velocity = 14 rev/min
 = Initial angular velocity = 14 rev/min
 = Final angular momentum
 = Final angular momentum
 = Final angular velocity
 = Final angular velocity
Here the angular momentum of the system is conserved

The final angular velocity is 0.2932 rad/s
