1.. A compact disc rotates from rest up to an angular speed of 31.4 rad/s in a time of 0.892 s. Through what angle does the disc turn while coming up to speed? a.14.0 rad b.15.0 rad c.16.0 rad d.17.0 rad 2..A race car accelerates uniformly from a speed of 40.0 m/s to a speed of 60.0 m/s in 5.00 s while traveling counterclockwise around a circular track of radius 4.00 x10^2 m. When the car reaches a speed of 50.0 m/s, find the angular speed. a. 0.125 rad/s b.0.075 rad/s c.0.375 rad/s d.0.475 rad/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.
