The figure below shows a bar AB with rollers on both ends sliding down a wall and sloped ground. At a given instance, roller A on the bar has velocity v$=\{3$j$\}$ m$/$s and acceleration a$=\{5$j$\}$ m$/$s$2.$

Draw a free$-$body diagram for bar AB including labels for the different position, velocity and acceleration vectors.

Determine the absolute velocity of the roller B$,$ and the bar's angular velocity at this instant.

Determine the absolute acceleration of the roller B$,$ and the bar's angular acceleration at this instant.
