16. 

The disk rolls without slipping such that it has an angular acceleration of = 4 rad/s2 and angular velocity of = 2 rad/s at the instant shown. Determine the accelerations of points A and B on the link and the link's angular acceleration at this instant. Assume point A lies on the periphery of the disk, 150 mm from C.

[A]. aA = (1.200i - 0.600j) m/s2, aB = 1.650i m/s2, "AB = 1.500 rad/s2
[B]. aA = (1.200i - 0.600j) m/s2, aB = 1.650i m/s2, "AB = 1.500 rad/s2
[C]. aA = (1.200i - 2.40j) m/s2, aB = 3.00i m/s2, "AB = 6.00 rad/s2
[D]. aA = (1.200i - 1.200j) m/s2, aB = 2.10i m/s2, "AB = 3.00 rad/s2
