## Question:

Pin $\Rho$ is constrained to move along the curve defined by the lemniscate r = (4$\sin { 2\theta }$ ) ft . If the angular position of the slotted arm OA is defined by $\theta$ = (3${t}^{3/2}$) rad, determine the magnitudes of the velocity and acceleration of the pin $\Rho$ when $\theta$ =60° .
