Answer

The object makes 10.3 revolutions during the first 4 seconds.

Work Step by Step

The area under the $\omega$ versus time graph is equal to $\theta$, the total angle through which the particle moves. $\theta = 65~rad$ We can convert the angle $\theta$ to revolutions. $\theta = (65~rad)(\frac{1~rev}{2\pi~rad})$ $\theta = 10.3~rev$ The object makes 10.3 revolutions during the first 4 seconds.
