No-slip Frictionless The ball is a solid sphere of radius 4.0cm and mass 0.14kg. the half-pipe has one side with sufficient static friction that we can assume no sliding will occur there. The ball is released from rest at a height of 0.77m above the bottom of the half-pipe on the no-slip side. What is its angular speed when it is on the frictionless side of the track? How high does it 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.
