A8.5. Estimate the magnitude and direction of a, and a,. (B) Find the magnitude and direction of the absolute acceleration of point P on link 3. \omega_{2}=1 \mathrm{rad} / \mathrm{s}

\mathrm{ccw} \alpha_{2}=1 \mathrm{rad} / \mathrm{s}^{2} \mathrm{ccw} A velocity analysis hasalready been completed,resulting in these values: \omega_{3}=0.333 \mathrm{rad} / \mathrm{s} \mathrm{cw} \omega_{4}=0.667 \mathrm{rad} / \mathrm{s} \mathrm{ccw} All horizontal and vertical edges are the same length, 1 meter.The diagonal edges are at 45°.
