(B) Let $T$ be the tension in the spring.For the $2 \,kg$ mass,the net force is $F - T = m_2 a_2$.Given $F = 10 \,N$,$m_2 = 2 \,kg$,and $a_2 = 2 \,m/s^2$:$10 - T = 2 	imes 2$$10 - T = 4$$T = 6 \,N$Now,for the $3 \,kg$ mass,the only horizontal force acting on it is the spring force $T$.Using Newton's second law,$T = m_3 a_3$:$6 = 3 	imes a_3$$a_3 = 2 \,m/s^2$Thus,the acceleration of the $3 \,kg$ mass is $2 \,m/s^2$.

What is the acceleration of $3 \,kg$ mass when the acceleration of $2 \,kg$ mass is $2 \,m/s^2$ as shown in the figure? (in $m/s^2$)
