PRACTICE / Angular displacement

Connect angular rate, acceleration and displacement

A wheel begins at angular velocity 2 rad/s and has constant angular acceleration 1 rad/s² in the same sense.

Through what angle does it turn before its angular velocity doubles?

1. A$4\ \mathrm{rad}$
2. B$8\ \mathrm{rad}$
3. C$2\ \mathrm{rad}$
4. D$6\ \mathrm{rad}$
