A solid uniform disk of mass M = 9.6 kg and radius R = 21 cm rests with its flat surface on a frictionless table (i.e., the axis of the cylinder is perpendicular to the table.) The diagram shows a top view. A string is wrapped around the rim of the disk and a constant force of F = 10.8 N is applied to the string. The string does not slip on the rim.

1)

What is the acceleration of the center of mass?

m/sec 2

2)

What is the angular acceleration about the center of mass?

/sec2

3)

The next 5 questions refer to a time 1.1 seconds after the force is first applied.

How far has the disk moved?

m

4)

Through what angle has the disk turned?

radians

5)

What is the translational speed of the center of mass of disk?

m/sec

6)

What is the angular velocity about the center of the disk?

/sec

7)

What is the total kinetic energy of the disk?

J
