A disk drive with a radius of 0.065 m starts rotating from rest with a constant angular acceleration. It takes 2 minutes and 50 seconds to complete ten revolutions. What is the linear (transitional) displacement of the rim of the disk drive after ten revolutions?
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.
