Concept explainers

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 w…
Question

A spherical object has a 32.1 m diameter. Its moment of inertia about a diameter is I = fMR2, where M is its mass, R is its radius, and f = 0.398.

Starting from rest, how long will it take in seconds, this object to roll without slipping 6.42 m down an incline that makes an angle of 37◦ with the horizontal? The acceleration of gravity is 9.8 m/s2 .
