W= rad/s b)what is the linear speed of its tip at this angular velocity of the plane is stationary on the tarmac? V= m/s c)what is the centripetal acceleration of the propeller tip under these conditions? Calculate it in meters per second squared ac = m/s^2 compare centripetal acceleration to the acceleration due to gravity g. Is the centripetal acceleration large or very small compared to g? ac/g= d) state what force provided this centripetal acceleration -the gravitational force -the rotary motor of the plane attached to the propeller -the Coriolis force -the force of kinetic friction
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.
