Boom $O A$ is being elevated by the rope-and-pulley arrangement shown. If point $B$ on the rope is given a constant velocity $v_{B}=9 \mathrm{ft} / \mathrm{sec},$ determine the angular velocity $\omega$ and angular acceleration $\alpha$ of the boom for $\theta=30^{\circ}$.
Rope Course and Climbing Wall. For a rope course and climbing wall, a guy wire $R$ is attached 47 ft high on a vertical pole. Another guy wire $S$ is attached 40 ft above the ground on the same pole. Domeck, Owner) Find the angle $\alpha$ between the wires if they are attached to the ground $50 \mathrm{ft}$ from the pole.

Identities: Pythagorean and Sum and Difference
The boom OAB pivots about point O, while section AB simultaneously extends from within section OA. Determine the velocity and acceleration of the pulley for the following conditions: θ = 17°, θ̇ = 2 deg/sec, θ̈ = 8 deg/sec², l = 10 ft, l̇ = 1.1 ft/sec, l̈ = -4.0 ft/sec². The quantities l̇ and l̈ are the first and second time derivatives respectively of the length l of section AB. Express your answers as vectors in the er and eθ directions.
