A wheel rotates with constant angular acceleration of 3.5 radians per second square. If the angular speed or velocity of the wheel is 2 radian per second at time =0, what angle does the wheel rotate between time =0 and time=2 seconds

Solution

$$\theta = \omega t + \frac {\alpha t ^ {2}}{2} = (2) (2) + \frac {1}{2} (3.5) (2) ^ {2} = 11 \mathrm{rad}.$$

Answer: 11 rad.
