Problem

A disk rotates such that its angular velocity is

4\,\text{rad/s}

at

t = 0\,\text{s}

and increases uniformly to

10\,\text{rad/s}

at

t = 2.0\,\text{s}

. It then remains constant at

10\,\text{rad/s}

until

t = 5.0\,\text{s}

. Determine the disk’s angular displacement

\Delta\theta

during the first

5.0\,\text{s}

.
