A solid sphere is placed at the top of a 45o incline. When released, it freely rolls down. What will be its linear speed at the foot of the incline which is 2.0 m below the initial position of the cylinder? A. 4.86 m/s B. 5.29 m/s C. 6.43 m/s D. 3.55 m/s
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.
