A solid disc of radius. 10 m is mounted on the vertical axis. A string of negligible masses wrapped around the rim of the disc passes over a small, lightweight, frictionless pulley as shown above and is tied to a block of mass .05 kg. The system is released from Russ, and a computer requires a velocity of the following block as a function of time, as shown below. Calculate the acceleration of the following block. Use your result from part a to calculate the rotational inertia of the desk. Calculate the angular momentum of the disc at time T equals . 4 five seconds. The disc removed and replaced with a hoop of the same mass and radius but with all of its mass concentrated near the rim of the hoop and connected to the axis by light weight spokes. The experiment is then repeated. Is the angular acceleration of the hoop greater than, less than, or The same as that of the solid disk?
