8. For a short time the bucket of the backhoe traces the path of the cardioid p = 25(1 - cos f) ft. The boom is rotating with an angular velocity of A = 2.3 rad/s and an angular acceleration of A = 0.25 rad/s2 at the instant shown. Please answer parts A and B with appropriate units.

For a short time the bucket of the backhoe traces the path of the cardioid r = 25(1 – cos 0) ft. The boom is
rotating with an angular velocity of 0 = 2.3 rad/s and an angular acceleration of 0 = 0.25 rad/s? at the
instant shown.
