A 85.6 g drink is left on a turntable causing it to turn with an angular speed of 8.20 rad/s. If the drink has coefficients of friction of μs = 0.830 and μk = 0.520 with the turntable, what is the furthest distance that the drink could have been placed from the centre of the turntable for the drink not to slide?
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.
