Determine the angular velocity, in radians per second, of 14.2 revolutions in 8 seconds

To answer this item, we use dimensional analysis and conversion factor, 1 revolution is equal to 2π rad. Using the concept and the given,
            
                        n = (14.2 revolutions / 8 seconds)(2π rad/1 rev)
                          n = 11.15 rad/s
Thus, the angular velocity is equal to 11.15 rad/s.
