The base structure of the firetruck ladder rotates about a vertical axis through 0 with a constant angular velocity ? = 10 deg/s. At the same time, the ladder unit 08 elevates at a constant rate ? = 7deg/s, and section AB of the ladder extends from within section OA at the constant rate of 0.5 m /s. At the instant under consideration, ? = 30?, OA = 9 m, and A8 = 6 m. Determine the magnitudes of the velocity and acceleration of the end 8 of the ladder.
