Large ships often have circular structures in their windshields. What is their purpose? Called clearview screens, they consist of a glass disk that is rotated at high speed by a motor (in the center of the circle) to disperse rain and spray. If the screen has a diameter of 0.40 m and rotates at 1700 rpm, the speed at the rim of the screen is 36 m/s. What is the centripetal acceleration at the rim of the screen? (A large centripetal acceleration keeps liquid from remaining on the screen. For comparison, recall that the acceleration due to gravity is 9.81 m/s2.) Express your answer to two significant figures and include appropriate units.
