At the instant θ = 60°, the telescopic boom AB of the
construction lift is rotating with a constant angular velocity
about the z axis of ω₁ = 0.5 rad/s and about the pin at A
with a constant angular speed of ω₂ = 0.25 rad/s.
Simultaneously, the boom is extending with a velocity of
1.5 ft/s, and it has an acceleration of 0.5 ft/s², both
measured relative to the construction lift. Determine the
velocity and acceleration of point B located at the end of
the boom at this instant.
