## Question:

The slotted link is pinned at O, and as a result of the constant angular velocity $\dot { \theta }$ = 3 rad/s it drives the peg $\Rho$ for a short distance along the spiral guide r = (0.4$\theta$) m , where $\theta$ is in radians. Determine the velocity and acceleration of the particle at the instant it leaves the slot in the link, i.e., when r = 0.5 m.
