The ball rolls without slipping up the incline and continues rolling at a constant but lower speed. Initial speed is vi = 2.62 m/s. The vertical height of the ramp is h = 0.47 m. There is no friction. What is the linear speed of the ball when it reaches the top of the ramp?
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.
