A wheel, starting from rest, rotates with a constant angular acceleration of 2.10 rad/s2. During a certain 2.00 s interval, it turns through 10.8 rad. (a) How long had the wheel been turning before the start of the 2.00 s interval? (b) What was the angular velocity of the wheel at the start of the 2.00 s interval?

Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
