A point mass of 0.33 kg is fixed to the end of a 1.23 m long string that is fixed at the other end. Initially at rest, the mass is made to rotate around the fixed end with an angular acceleration of 3.14 rad/s2 . What centripetal force acts on the mass after 5.34 seconds? Assume that all quantities are good to 3 significant figures, All numeric answers should be entered rounded to 3 significant figure.
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.
