9. As a result of friction, the angular speed of a wheel changes with time according to dθ/dt = ω0e−σt, where ω0and σ are constants. The angular speed changes from an initial angular speed of 4.424rad/s to 3.250rad/s in 3.92s. Determine the magnitude of the angular acceleration after 2.67s. A)0.282 rad/s2 B)0.284 rad/s2 C)0.286 rad/s2 D)0.288 rad/s2 E)Noneofthese
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.
