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 blocks is

$a_{A} = \frac{g}{7}$
$a_{B} = 0 m / s^{2}$
$a_{c} = \frac{5}{7} m / s^{2}$
$2 a_{C} = a_{A}$

The correct answer is: $straight a subscript straight A equals straight g over 7$

A light string fixed at one end to a clamp on ground passes over a fixed pulley and hangs at the other side. It makes an angle of with the ground. A monkey of mass 5 kg climbs up the rope. The clamp can tolerate a vertical force of 40 N only. The maximum acceleration in upward direction with which the monkey can climb safely is (neglect friction and take $straight g equals 10 straight m divided by straight s squared$ ):
