A handbrake is applied to a rotating flywheel, initially moving counterclockwise, causing it to slow down with a constant angular acceleration of magnitude 5.00 rad/s2. Immediately after the handbrake is applied, the flywheel rotates through 52.9 rad during a 4.00 s time interval. What is the angular speed (in rad/s) of the flywheel at the end of this time 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.
