Dymanics Problem 2... URGENT (Will rate lifesaver)

Course Textbook Chapter Problem
Classical Mechanics Engineering Mechanics Dynamics 11th edition R.C. Hibbeler N/A N/A
Question Details:

Pin P is attached to the collar shown; the motion of the pin is guided by a slot cut in bar BD  and by the collar that slides on rod AE.  Rod AE rotates with a constant angular velocity of 5 rad/s clockwise and the distance from A to P increases at a constant rate of 2 m/s. 

(a)    Show that ωBD = 0 and VP/B = 2*sqrt(2)*ei45 .

      (b) Determine at the instant shown the angular acceleration of bar BD and the relative acceleration of pin P with respect to bar BD.  (Answer: αBD = 37.5 [rad/s2], aP/BD = 7.07ei45 )
