In the arrangement shown pulley and thread are mass less. Mass of plate is 20 kg and that of boy is 30 kg.
Then :

In the arrangements shown in the figure masses of each ball is 1 kg and mass of trolley is 4 kg . In the figure, shell of mass 1 kg moving horizontally with velocity v = 6 ms^(-1) collides with the ball and get stuck to it then its maximum deflection of the thread (length 1.5 m ) with vertical
