The crane has a boom of length = 24 m and is revolving about the vertical axis at the constant rate of 2 rev/min in the direction shown. Simultaneously, the boom is being lowered at the constant rate = 0.10 rad/s. Calculate the magnitudes of the velocity and acceleration of the end P of the boom for the instant when it passes the position β = 30°.
