Question
what is the answer?
A meter stick of mass m, = 0.25 kg rotates about an axis passing through one end as shown in
figure below. The rotational inertia of the meter stick I = 0.09 kgm2 . As the stick reaches its
lowest position, it collides with a m, = 0.15 kg putty that sticks to the end of the meter stick. The
stick's angular speed just before collision is w, = 2.1 rad/s, what is the angular speed of the
stick-putty system immediately after collision?
