Application of Newtons laws

Question

In the following arrangement, the system is initially at rest. The 5-kg block is now released. Assuming the pulleys and string to be massless and smooth, the acceleration of block C will be

Moderate

A

Zero
B

$2.5 {ms}^{- 2}$
C

$10 / 7 {ms}^{- 2}$
D

$5 / 7 {ms}^{- 2}$

Solution

$For A : 5 g - T = 5 (2 C)$
$For C : 2 T - 8 g = 8 C \Rightarrow C = \frac{8}{14} = \frac{5}{7} {ms}^{- 2}$
