## 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 radial and transverse components of the velocity and acceleration of $\Rho$ at the instant $\theta$= $\pi$ /3 rad.
