## Question:

The slotted arm AB drives pin C through the spiral groove described by the equation r = (1.5$\theta$) ft , where $\theta$ is in radians. If the arm starts from rest when $\theta$ = 60° and is driven at an angular velocity of $\dot {\theta}$ = (4t) rad/s , where t is in seconds, determine the radial and transverse components of velocity and acceleration of the pin C when t = 1 s .
