The propeller of a World War II fighter plane is 2.05 m in diameter. a) what is the angular velocity in radians per/sec if it spins at 1280 rev/min? b) what is the linear speed in m/s of its tip at this angular velocity if the plane is stationary on the tarmac? c) what is the centripital acceleration of the propellar under these conditions in m/s^2?
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.
