A 20 kg block placed on a level frictionless surface is attached to a cord which passes over two small frictionless pulleys,as shown in figure-2.167,to a hanging block originally at rest 1m above the floor. If the hanging block strikes the floor 2 s after the system is released, the weight of the hanging block is :

A block A (mass 4M) is placed on the top of a wedge block B of base length l (mass=20M) as shown in figure. When the system is released from rest. Find the distance moved by the block B till the block A reaches ground Assume all surfaces are frictionless.

Refer the system shown in the figure. Block is siding down the wedge. All surfaces are frictionless. Find correct statement (s)
