Imagine a disc which has a diameter of 2.00m. The angular velocity of the spinning disk is 305rev/min. a) What is the angular velocity of the disk in radians per second? b) What is the linear speed of a point on the rim of the disk? (m/s) c) Find the angular accleration (in revolutions per minute-squared)that will increase the disk's angular velocity to 1000 rev/min in 60 s. Assume the acceleration is constant
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.

a) What is the angular velocity of the disk in radians per second?
b) What is the linear speed of a point on the rim of the disk? (m/s)
c) Find the angular accleration (in revolutions per minute-squared)that will increase the disk's angular velocity to 1000 rev/min in 60 s. Assume the acceleration is constant.
d) How many revolutions does the disk make during this 60 s accleration?
