The ability of the human eye to rapidly rotate was studied using contact lenses fitted with accelerometers. While a subject, whose eyeball has radius 1.25 cm, watches a moving object her eyeball rotates through 20.0° in a time interval of 69.6 ms. a. What is the magnitude of the average angular velocity of the eye? asnwer in rad/s b. Assume that the eye starts at rest, rotates with a constant angular acceleration during the first half of the interval, and then the rotation slows with a constant angular acceleration during the second half until it comes to rest. What is the magnitude of the angular acceleration of the eye? answer in rad/s^2 c. What tangential acceleration would the contact-lens accelerometers record in this case? answer in m/s^2

A rigid body rotates about a fixed axis with a constant angular velocity. Which one of the following statements is true concerning the tangential acceleration of any point on the body? O The tangential acceleration is zero m/s². The tangential acceleration does not depend on the angular velocity. O The tangential acceleration depends on the change in the centripetal acceleration. O The tangential acceleration is constant, but not equal to zero m/s², in both magnitude and direction. O The tangential acceleration is equal to the centripetal acceleration.
