A 14.0kg box, resting on a horizontal frictionless surface, is attached to a 4.00kg weight by a thin, light wire that passes over a frictionless pulley. The pulley has the shape of a uniform solid disk (3.00kg) and diameter of 0.500m. a) What is the acceleration of the weight downward? b) During the fall, what is the tension in the string holding the weight? c) What is the tension in the string pulling the 14.0kg box?
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.
