A 0.1 kg solid disc has a radius of 0.2 m. The moment of inertia of a solid disc is I = ½ m r2. EXAM The disc initially rolls with a velocity of 2 m/s along a horizontal surface. It then rolls up a ramp and briefly stops when it reaches a height h. The disc rolls without slipping on both surfaces. a) What is the angular velocity of the disc when it is on the horizontal surface? b) What is the speed of a point on the very top of the disc when the disc is on the horizontal surface? c) Use Conservation of Energy to find the maximum height of the disc, h. d) If the disc were replaced with a thin ring (same mass, same radius, same initial speed), would it roll higher, less high, or the same height? No calculations required. Briefly explain your answer! e) If there were no friction (the disc slides instead of rolling), but the disc still has the same initial speed, would it roll higher, less high, or the same height?
5. A rod of length Do and mass 2Mo is at rest on a flat, horizontal surface. One end of the rod is connected to a pivot that the rod will rotate around if acted upon by a net torque. A lump of clay of mass mo is launched horizontally toward the center of the rod with velocity Vo, as shown in the figure. After the clay collides with the rod, the clay sticks to the rod and both objects rotate around the pivot with the common angular velocity wo. The rotational inertia of the clay-rod system is Is. What is clay's angular velocity immediately after the collision? mo Vo Do 2Mo
