An object with a mass of m = 2 kg is located on an inclined plane at an angle of 37o with the horizontal and the friction coefficient between the object and the inclined plane is 0.25. In the reel with a radius of R = 20 cm and a mass of M = 4kg, there is no friction and the other end of the rope wound on it is attached to the object. What will be the angular acceleration of the pulley in rad / s2 if the object is released? (g = 10 m / s2, LaTeX: I = \ frac {1) {2} MR ^ 2I = 12MR2, cos 37o = 0.8, sin 37o = 0.6)
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.
