## Question:

The peg is constrained to move in the slots of the fixed bar CD and rotating bar AB . When $\theta$ = 30° , the angular velocity and angular acceleration of arm AB are $\dot {\theta}$ = 2 rad/s and $\ddot {\theta}$ = 3 rad/${s}^{2}$ , respectively. Determine the magnitudes of the velocity and acceleration of the peg $\Rho$ at this instant.
