Transcribed Image Text:**Problem Description**
A 3 kg uniform disk has a radius of 2 m. An external torque of 10 N·m is applied to the outside of the hoop for 10 seconds.
**Diagram Explanation**
The diagram shows a uniform disk with the following labeled points:
- \(O\) is on the axis of rotation.
- \(m\) represents mass.
- \(R\) indicates the radius of the disk.
- \(C\) is the center point of the disk.
- The disk is depicted in a horizontal orientation.
**Questions**
a. What is the angular acceleration?
b. What is its angular speed after 10 seconds?
c. How much kinetic energy (KE) does the disk have after 10 seconds?
d. How much work did the external torque do on the disk?
e. What is the linear velocity of a point on the outside of the disk after 10 seconds?
