NASA's Ames Research Center in Mountain View, California, houses a 20g centrifuge used to conduct research and training to solve real world problems related to the effects of acceleration on systems. It consists of a horizontal rail system with a 58-foot diameter mounted on a central axis, as shown in the figure below. An astronaut is using the centrifuge for training on high accelerations during spaceflight. The astronaut is seated 29.0 ft from the axis of rotation. At what rotation rate, in revolutions per second, will the astronaut experience a centripetal acceleration of 17.4g?

Calculate the centripetal acceleration, ac, of various objects.   Yelena is driving her car on a dry, non-slippery road. The car moves forward with a speed of 34.1 m/s. What is the centripetal acceleration of the tire which has a radius of 0.45m? Answer ______ m/s^2   Arek is riding her bicycle on a non-slippery bike path. The wheel has a radius of 677 mm. The bike moves forward at 9.25 m/s. What is the wheels centripetal acceleration? Answer ______ m/s^2   Jolie the hamster is using his hamster wheel which has a diameter of 26.6 cm. a point on the wheel is moving at 0.19 m/s. What is the hamster wheels centripetal acceleration? Answer ______ m/s^2
