2. The inversion of a slider-crank mechanism shown below is driven by link 2. (A: 12 points) Estimate the angular accelerations of links 3 and 4. (B: 8 points) Estimate

the linear acceleration vectors for point C and point P, both located on link 3. (C: 5 points) Estimate the linear acceleration vector for point Q on link 2.Report both magnitude and direction for all of the above quantities. R_{P A}=R_{C P}=R_{B C}=2 \text { in } \begin{array}{l} \omega_{2}=1 \mathrm{rad} / \mathrm{s} \mathrm{ccw} \\ \alpha_{2}=1 \mathrm{rad} / \mathrm{s}^{2} \mathrm{ccw} \end{array}
