Problem $5.(20$pts$)$ Determine the angular acceleration of link BC and the acceleration of the piston C at

the instant shown below where the wheel has angular velocity of $=6ra\frac{d}{s}$ and angular acceleration

$=3ra\frac{d}{s^2}$

please use kinematics i dont want $anAI$ generated response i want a real person $to$ walk $me$ through step $by$ step how $to$ find the angular accelleration $of$ the link $BC$ and the acceleration $of$ the piston $C.$
