assume the ball is a solid sphere of radius 2.9 cm and mass0.14 kg. If the ball is released from rest at a height of 0.78 m abovethe bottom of the track on the no-slip side, (a) what is its angularspeed when it is on the frictionless side of the track? (b) How highdoes the ball rise on the frictionless side?
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.
