The propeller of an aircraft is spinning at 15 rev/s when the pilot shuts off the engine. The propeller reduces its angular velocity at a constant 3.2 rad/s? for a time period of 37 s. What is the rotation rate (in rad/s) of the propeller in 37 s? rad/s Is this a reasonable situation?
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.
