Field trip to amusement park

Classical Mechanics Level 1

During their physics field trip to an amusement park, Tyler and Maria took a ride on the Whirligig, which has long swings spinning in circles at relatively high speeds. As part of their lab assignment, they estimated that the riders were making a full circle of radius $6.5 \text{ m}$ every $5.8$ seconds. Determine the approximate speed of the riders on the Whirligig.
