A discus thrower starts from rest and begins to rotate with a constant angular acceleration of 2.4 rad/s2rad/s2 . Part A How many revolutions does it take for the discus thrower's angular speed to reach 5.0 rad/srad/s ? Express your answer using two significant figures. Part B How much time does this take? Express your answer using two significant figures.
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.
