Rotational Motion Quiz: 1. During their physics field trip to the amusement park, Masen and his son 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, Masen and his son estimate that the riders travel through a circle with a radius of 8.5 m and make one turn every 6.5 seconds. Determine the speed of the riders on the Whirligig. During the spin cycle of a washing machine, the clothes stick to the outer wall of the barrel as it spins at a rate as high as 900 revolutions per minute. The radius of the barrel is 25 cm. a. Determine the speed of the clothes (m/s) which are located on the wall of the spin barrel. b. Determine the acceleration of the clothes. 3. A 78-kg pilot at an air show performs a loop de loop with his plane. At the top of the 105-m radius loop, the plane is moving at 92 m/s. Determine the normal force acting upon the pilot
