Both the blocks have equal mass m. String is massless and inextensible. Acceleration of mass A is

____ $m / s^{2}$ .

A ____ $m / s^{2}$

Answer:

Solution:

String constraint: $a_{B} = 3 a_{A}$

For A: $\frac{3 T}{2} - m g = m a_{A}$ ; for B: $m g - \frac{T}{2} = m a_{B}$

Eliminating $T$ : $2 m g = 3 m a_{B} + m a_{A} = 10 m a_{A}$

$a_{A} = \frac{g}{5} = 2$ m/s $^{2}$
