Question:
The crane shown rotates at the constant rate ω1 = 0.25 rad/s; simultaneously, the telescoping boom is being lowered at the constant rate ω2 = 0.40 rad/s. Knowing that at the instant shown the length of the boom is 20 ft and is increasing at the constant rate u = 1.5ft/s, determine the velocity and acceleration of Point B.
