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.

7.0 \text{ m/s}

12.0 \text{ m/s}

14.0 \text{ m/s}

3.0 \text{ m/s}

Distance covered by riders in one revolution = $2\pi r$

It is given that riders cover one revolution in 5.8 s $\Longrightarrow$

Speed = $\frac{2\pi r}{5.8}$ = 7.0 m/s
