Problem $15\mathrm{.}136$ modified

For the oil pump rig shown, link $AB$ causes the beam BCE to oscillate as the crank $OA$ revolves. It is known that $OA$ has a radius of $0\mathrm{.}6$ m and a constant clockwise angular velocity of $2\mathrm{.}0ra\frac{d}{sec}.$

Determine the angular velocities of link $AB$ and beam BCE.${}_{AB}=k(ra\frac{d}{s})$ and ${}_{\text{B}\text{C}\text{E}}=k(ra\frac{d}{s})$

Determine the angular accelerations of link $AB$ and beam BCE.$a_{AB}=k(ra\frac{d}{s^2})$ and $a_{\text{B}\text{C}\text{E}}=(ra\frac{d}{s^2})$

Determine the velocity and acceleration of point $E.v_E=q,$ i $+j(\frac{m}{s})$ and $a_E=i+(\frac{m}{s^2})$
