Ascientist makes a device to catch baseballs. a long bar of total mass 2.2kg and length 1.2m is fixed at its center. it catches a ball of mass 0.15kg moving at v=16m/s in a box at one of its ends. ignore the mass of the catcher box for this problem. what is the angular velocity of the system after the ball is caught?

Ответ:
ωf = 4.53 rad/s
Explanation:
By conservation of the angular momentum:
Ib*ωb = (Ib + Ic)*ωf
Where
Ib is the inertia of the ball
ωb is the initial angular velocity of the ball
Ic is the inertia of the catcher
ωf is the final angular velocity of the system
We need to calculate first Ib, Ic, ωb:
ωb = Vb / (L/2) = 16 / (1.2/2) = 26.67 m/s
Now, ωf will be:
