P18. The track shown in the figure consists of two parts: the left part has rough surface, the right part is approximately frictionless. A solid, uniform cylin- der of radius R is released from height h on the left side of the track. Here the friction is so large that the cylinder starts to roll without slipping. m h h' H = 0 a) Find the angular speed and the speed of the center of the cylinder when it passes through the lo- west point of the track. b) What is the height h' reached by the cylinder on the other side of the track?

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.
