The setup you used for the rotational motion experiment is shown in the diagram. A student decided to try a different method for measuring the moment of inertia of the disk. He used a force transducer to measure the tension in the thread and found it to be 0.976 N when the hanging mass m was 100.0 g. The hanging mass started off 0.800m from the floor, the diameter of the pulley about which the thread was wound was 2.00 cm, and the diameter of the disk was 25.0 cm. (a) how long a time was required for mass m to strike the floor? (b) what was the tangential acceleration of a point on the rim of the disk? (c) what was the mass of the disk? (note: Idisk= (1/2)MR^2) )
