At the instant shown, the frame of the excavator travels forward in the y direction with a velocity of 2 m/s and an acceleration of 1 m/s², while the cab rotates about the z axis with an angular velocity of = 0.3 rad/s, which is increasing at At the same instant θ = 60°, and the boom OBC has an angular velocity of which is increasing at both measured relative to the cab. Determine the velocity and acceleration of point C on the grapple at this instant.
