Problem

A solid disk of mass

5.0\,\text{kg}

and radius

0.20\,\text{m}

is free to rotate about its central axis. A

10\,\text{N}

force acts tangentially at its rim. What is the magnitude of the disk’s angular acceleration? a)

25\,\text{rad/s}^2

20\,\text{rad/s}^2

40\,\text{rad/s}^2

10\,\text{rad/s}^2
