In this question use $g = 9.8$ m s $^{-2}$

Two particles $A\,$ and $B$ , of masses 4 kg and 6 kg respectively, are connected by a light inextensible string passing over a smooth fixed pulley.

The particles hang freely with the string vertical on both sides of the pulley.

The system is released from rest with the string taut, with $A\,$ resting on horizontal ground and $B\,$ hanging 2 metres above the ground, as shown in the diagram below.

Figure for question 4

Find the speed of $B\,$ at the instant it reaches the ground.

After $B\,$ reaches the ground, $A\,$ continues to move upwards freely. Find the further height risen by $A\,$ before it comes to instantaneous rest.
