Question
20–49. At the instant shown, the backhoe is traveling
forward at a constant speed vo = 2 ft/s, and the boom ABC
is rotating about the z axis with an angular velocity
w, = 0.8 rad/s and an angular acceleration ở, = 1.30 rad/s.
At this same instant the boom is rotating with w = 3 rad/s
when on = 2 rad/s², both measured relative to the frame.
Determine the velocity and acceleration of point P on the
bucket at this instant.
w = 3 rad/s
wz = 2 rad/s
W = 0.8 rad/s
wi = 1.30 rad/s²
