Question

During their physics field trip to the amusement park, Tyler and Maria took a rider on the Whirligig. The Whirligig ride consists of long swings which spin in a circle at relatively high speeds. As part of their lab, Tyler and Maria estimate that the riders travel through a circle with a radius of 6.5 m and make one turn every 5.8 seconds. Determine the speed of the riders on the Whirligig. (Give your answer to the nearest whole number

Answer 1

$$v=\frac{2\pi r}{T}$$

$$v=\frac{2\pi (6.5)}{5.8}=7.0\frac{m}{s}$$
