The arm AB of length 16 ft is used to provide an elevated
platform for construction workers. In the position shown, arm
AB is being raised at the constant rate de/dt = 0.25 rad/s;
simultaneously, the unit is being rotated about the Y axis at the
constant rate ₁ =0.15 rad/s. Knowing that 20°, determine
the velocity and acceleration of Point B.
