The WindSeeker ride at Canada's Wonderland lifts riders up to 300 feet into the air while spinning them around in a 15.4 m radius circle. The WindSeeker starts its circular motion from rest with a constant angular acceleration of 0.0174 rad/s2. It maintains that angular acceleration for 46.8 s, after which the angular speed remains constant for the rest of the ride - another 131 s. During the entire time on the WindSeeker, what angle does the rider pass throug

A platform is rotating with an angular speed of 3.00 rad/s and an angular acceleration of 11.0 rad/s². At a point on the platform that is 1.26 m from the axis of rotation, what is the magnitude of the total acceleration a?

Human centrifuges are used to train military pilots and astronauts in preparation for high-g maneuvers. A trained, fit person wearing a g- suit can withstand accelerations up to about 9g (88.2 m/s2) without losing consciousness. HINT (a) If a human centrifuge has a radius of 5.17 m, what angular speed (in rad/s) results in a centripetal acceleration of 9g? X rad/s (b) What linear speed (in m/s) would a person in the centrifuge have at this acceleration? m/s

A 3.45-kg centrifuge takes 99 s to spin up from rest to its final angular speed with constant angular acceleration. A point located 6.9 cm from the axis of rotation of the centrifuge moves with a speed of 178.2 m/s when the centrifuge is at full speed. What is the angular acceleration (in rad/s2) of the centrifuge as it spins up?
