A car makes a 50-m-radius turn on a flat road with no banking. The car speeds up until a book on the floor overcomes friction and starts to slide outward. If the coefficient of static friction is 0.45, what was the speed of the car when the book began to slide?
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.
