A bar moves along a path without rotating as shown in $($Figure $1).$ The position of point $B$ can be described by the equation $r_B=(3+3\mathrm{.}8t)i+(5t+0\mathrm{.}6t^2)j,$ where the coordinates are in meters when $t$ is in seconds. The dimensions of the bar are $L_1=0\mathrm{.}9m$ and $L_2=2\mathrm{.}2m,$ and the angle is $=67.$
