Problem $17\mathrm{.}089-$ Rod sliding on two surfaces $-$ DEPENDENT MULTI$-$PART PROBLEM $-$ ASSIGN ALL PARTS

The uniform thin bar, which is leaning on the incline, is released from rest in the position shown and slides in the vertical

plane. The contacts between the bar and the surface at ends A and $B$ have negligible friction. Consider $m=3kg,L=0\mathrm{.}73$

$m,=45,$ and $=30.$

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

Problem $17\mathrm{.}089.$b $-$ Rod sliding on two surfaces: angular acceleration

Determine the angular acceleration of the bar immediately after it is released. $($Round the final answer to four decimal places. Do not

include a minus sign in your response.$)$

The angular acceleration of the bar is

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