Just as you had done in your lab, imagine that you have a solid uniform disk (same as a uniform cylinder) with a string wound around its rim. (These disks are truly solid and do not have an inner radius like those in the lab.) You pull the string with a force having a magnitude 15 N. The disk has a mass of 5 kg and a radius of 20 cm. The disk is free to rotate without friction about a fixed axis going through its center.

a.) What is the angular acceleration of the disk?

b.) Suppose that you start pulling the string when the disk was at rest. What is the angular velocity of the disk after 2 s?

c.) What is the angular acceleration of the disk? Hint: look at the equation for angular acceleration in the lab manual.

d.) What is the acceleration of the falling mass?

e.) What is the tension on the string?
