$1 \,\,m/s^2$ upwards

Vedclass · Answer

$l_{1}+l_{2}+l_{3}+2 l_{4}=$ constant

$\frac{d l_{1}}{d t}+\frac{d l_{2}}{d t}+\frac{d l_{3}}{d t}+2 \frac{d l_{4}}{d t}=0$

$\frac{d^{2} l_{1}}{d t^{2}}+\frac{d^{2} l_{2}}{d t^{2}}+\frac{d^{2} l_{3}}{d t^{2}}+2 \frac{d^{2} l_{4}}{d t^{2}}=0$

$2+(2-1)-1+2 \frac{d^{2} 1_{4}}{d t^{2}}=0$

$a_{B}=-1 m / s^{2}$

$a_{B}=1 m / s^{2} \uparrow$
