The 30 -kg wheel has a radius of gyration about its center of $75 \mathrm{mm}$ and is rotating clockwise at the rate of 300 rev/min when it is released onto the incline with no velocity of its center $O .$ While the wheel is slipping, it is observed that the center $O$ remains in a fixed position. Determine the coefficient of kinetic friction $\mu_{k}$ and the time $t$ during which slipping occurs. Also determine the velocity $v$ of the center 4 seconds after the wheel has stopped slipping.

Momentum and Collisions:Two balls are placed on top of each other. The top ball has 3.00 cm diameter and the bottom ball has 9.00 cm. The bottom of the lower ball is exactly 1.00 m above the ground. Both fell 1.00 m reaching the same maximum speed. Then lower ball bounces elastically off the floor and collides elastically with the upper ball. How high did the top ball get?

A 5-kg rat is launched from a catapult. This catapult is 75% efficient in converting elastic potential energy to kinetic energy. It is equipped with a twisted rope spring with a k value of 1240 N/m. the spring suffers a stretch of 1.35 m in the process of arming the catapult. determine the rat's initial speed, and its horizontal range, assuming it is level ground and a 45 degrees release angle.
