a centrifuge accelerates at a constance angualr acceleration from rest to 11,000 revolution per minute in 25s. the sample spins at a radius of 0.15m. a. what is the final angular velocity of sample in rad/s? b. what is the angular accelertaion of the sample in rad/s^2? c. what is the tangential acceleration of the sample as the centrifuge spins up? d. what is the centripetal acceleration of the sample at full speed?
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.
