9.37 The flywheel of a gasoline engine is required to give up 540 JJ of kinetic energy while its angular velocity decreases from 640 rev/min to 540 rev/min What moment of inertia is required? Express your answer in kilogram meters squared.
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.
