A pulley driving belt has a diameter of 13 feet and is turning at 30 times per minute. Find a) the angular velocity and linear velocity of the curve. b) model a cosine curve for the above information if the pulley system is 2 feet above the ground and draw the graph of it.
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.
