Problem 9)A nonuniform rod is attached to a hinge so it can pivot at the ground and is vertically balanced. It has a length of and a total mass of . It gets denser as it is higher from the ground so it has a density of , where is an unknown constant. A point mass is moving horizontally with velocity immediately before it collides completely inelastically with the pole at a height from the pivot and sticks to the rod. This causes the rod to lose balance and fall to the ground. a) What is the constant ?b) What is the angular velocity of the rod immediately after the collision?c) What is the angular velocity of the rod as it hits the ground?

3. [10 pts] Poles and zeros. The locations of the poles and zeros of $X(z)$ are depicted in the z-plane in the following figures: $-rac{3}{4}$ 0 $rac{1}{3}$ $rac{3}{2}$ (a) (b) $1+j$ $i$ $x$ $-1$ 0 1 $1-j$ $-i$ $x$ (c) $-1$ $rac{1}{2}$ $rac{3}{4}$ $-rac{3}{4}$ For each case, identify all valid regions of convergence (ROCs) for $X(z)$. Specify whether the time signal corresponding to each valid ROC is right sided, left sided or two sided.
