A stone is suspended from the free end of a wire that is wrapped around the outer of a pulley as shown. The pulley is a solid cylinder with mass 10.0 kg and radius 30.0 cm. You measure that the stone travels 12.6 m in the first 3.00 s starting from rest. What is (a) the tension in the wire and (b) the mass of the stone?
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.
