Problem 10P
A 3.5-inch floppy disk in a computer rotates with a period of 2.00 × 10− 1 s. What are (a) the angular speed of the disk and (b) the linear speed of a point on the rim of the disk? (c) Does a point near the center of the disk have an angular speed that is greater than, less than, or the same as the angular speed found in part (a)? Explain. (Note: A 3.5-inch floppy disk is 3.5 inches in diameter.)

ANSWER:
Step 1 of 3:-
a)
Here we have to find the angular speed of the disk.
The diameter of the disk is,
.
The radius will be,
.
The time period is given as,
.
The angular speed will be,
.
The angular speed will be 31.41 rad/s.
