You find an interesting looking ball but can't tell if it's solid or hollow, so you design an experiment: The mystery ball is rolled along a horizontal surface with an initial translational speed of v= 2.7 m/s. Then the ball rolls up an incline and eventually stops after climbing up a vertical distance of h = 0.52 m, as shown in the figure. %3D Based on your experiment, is the ball solid or hollow? Use calculations to support your answer. Assume the ball rolls without slipping. Note: you do not need to know the mass or radius of the ball to answer this problem. 1>

Q: At what speed, as a fraction of c, does

A:

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.
