The position equations have been solved, yielding $=183\mathrm{.}33$deg and $s=2\mathrm{.}993ft.$ Write the scalar component position equations and differentiate to obtain the velocity and acceleration equations. Determine the angular velocity and angular acceleration of link $3$ and the velocity and acceleration of slider $4.$ Assume crank $2$ to be rotating $40ra\frac{d}{s}CW,$ constant.

$a=2\mathrm{.}0ft$

$b=4\mathrm{.}0ft$

$h=1\mathrm{.}5ft$

$=60$deg
