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 with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.

Question

1) James is driving around a curve with a radius of 20m, at an angle of 12 degrees banked and he has rubber tires on cement. What is the formula for the maximum velocity (derive it). And what is that speed? (use the static coefficient of friction).
