A ferris wheel is rotating clockwise at an angular speed of 1.83 rpm. When the ride operator activates the brakes, the ferris wheel steadily slows down to a stop whilst turning through 1.19 revs. Use radians as the standard unit for angles. Initial angular speed is 0.192 rad/s. The angle that the ferris wheel rotates through during the breaking period is 7.48 rad. What is the magnitude of the angular acceleration of the ferris wheel?
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.
