Collar C moves along rod BA with a velocity of 3 m/s and an acceleration of .5 m/s^2 both directed from B towards A and measured relative to the the rod. At the same instant, rod AB rotates with the angular velocity and angular acceleration shown. Determine the collar's velocity and acceleration at this instant.
