The base structure of the firetruck ladder rotates about a vertical axis through O with a constant angular velocity = 9.1 deg/s. At the same time, the ladder unit OB elevates at a constant rate p = 8.8 deg/s, and section AB of the ladder extends from within section OA at the constant rate of 0.42 m/s. At the instant under consideration, p = 25°, OA = 8.2 m, and AB = 5.8 m. Determine the magnitudes of the velocity v and acceleration a of the end B of the ladder.
