2. For the mechanism shown in Figure 2 , link 2 rotates at an angular acceleration of \( \alpha_{2}=2 \mathrm{rad} / \mathrm{s}^{2} \) (ccw) and an angular velocity of \( \omega_{2}=7 \mathrm{rad} / \mathrm{s}(\mathrm{ccw} \) ). Slider 5 moves with a constant linear velocity of \( 0.8 \mathrm{~m} / \mathrm{s} \) to the right. a) Please determine the velocity of point \( A \). [5 marks] b) Please determine the velocity of point \( B \). \( [10 \) marks \( ] \) c) Please determine the velocity of point \( C \).
