A small 0.500 kg disk--it is small enough to be modelled as a point-mass--collides with and sticks to one end of a long thin rod of mall 1.50 kg. The other end of the rod is fixed, and the pair lie on a frictionless table. The disk is initially at rest, and the rod is moving with an initial angular speed of 4.00 rad/s.

**SHOW WORK PLEASE**

(a) If the rod is 1.00 m long, what is its moment of inertia about the fixed end?

(b) What is the initial angular momentum of the system?

(c) What is the final angular speed of the rod?

(d) What is the final translational speed (instantaneous) of the disk?

(e) What fraction of energy was retained in ths collision? You are calculating the ratio Ef/Ei where Ef is the final and Ei is the initial energy of the system.
