Conservation of linear and angular momentum

step 1. finding the velocity of the ball leave from the track.

using the conservation of energy to solve the velocity 

Depends on the experiment, using the kinetic equation to solve the velocity.

Step 2. Determent the moment of inertia of the system

the same method we used in the last few labs.

Step 3. Do the experiment as the ball release from the marked starting point, the ball will catch by the catcher.

 The calculation for the final angular velocity.

The actual value of the angular velocity is 1.64 rad/s.

Those values are pretty close therefore our experiment can conform the conservation of linear and angular momentum.
