$15\mathrm{.}106$ In Prob. $15\mathrm{.}105,$ determine the point of the rod that $(a)$ has no

acceleration, $($b$)$ has an acceleration of $2\mathrm{.}4\frac{m}{s^2}$ to the right.

$15\mathrm{.}105$ A $900-mm$ rod rests on a horizontal table. A force $P$ applied as

shown produces the following accelerations: $a_A=3\mathrm{.}6\frac{m}{s^2}$ to the

right, $=6ra\frac{d}{s^2}$ counterclockwise as viewed from above. Deter$-$

mine the acceleration $($a$)$ of point $G,(b)$ of point $B.$
