A ball on the end of a string is spinning around a circle with a radius of 5 centimeters. If in 16 seconds a central angle of 1/10 radian has been covered, what is the angular speed of the ball?

Solution

Angular speed is in radians: radians per <1 unit of specified time>

Now, angular speed =(1/10)/16

= (1/160)radians per second
