In the figure-2.216, the masses A and B are of 4kg and 12 kg respectively. When the system is released from rest, find the time after which the block B will hit the ground.

If the system is left from rest find the time taken by the 8kg block to reach the ground.

Two blocks A and B are shown in figure have masses 5 kg and 4kg respectively. The system is released from rest. The speed of B after A has travelled the distance 1 m along the incline is (take g= 10m/s^2 ,pulleys and strings are ideal and plane is smooth)

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.

Consider the system shown in fig. the system is released from rest, find the tension in the cord connected between 1kg and 2 kg blocks.

The blocks A and B shown in the figure have masses M_A = 5 kg and M_B = 4 kg . The system is released from rest. The speed of B after A has travelled a distance 1 m along the incline is

Consider the system shown in fig. the system os released from rest, find the tension in the cord connected between 1kg and 2 kg blocks.

Consider the system shown in fig. the system os released from rest, find the tension in the cord connected between 1kg and 2 kg blocks.

Three blocks A, B and C havig masses m kg, 2kg and 3 kg are attached by massless strings and ideal pulleys as shown in the figure. When the system is realeased from rest if the block A remains stationary. the mass of block A is
