Problem $15\mathrm{.}133$ modified

It is known that at the instant shown bar $AB$ has an angular velocity of $9\mathrm{.}5ra\frac{d}{s}$ and an angular acceleration of $3\mathrm{.}4ra\frac{d}{s^2},$ both clockwise.

Determine the angular velocity and angular acceleration of rod $BD*{}_{BD}=k(ra\frac{d}{s})$ and $a_{BD}=(ra\frac{d}{s^2}).$

Determine the angular velocity and angular acceleration of rod $DE*{}_{DE}=k(ra\frac{d}{s})$ and $a_{DE}=(ra\frac{d}{s^2}).$
