In the arrangement shown in figure, `m_A = 1kg and m_B = 2kg` , while all the pulleys and strings are masslesss and frictionless. At t = 0, a force F = 10t starts acting over central pulley in vertically upward direction. If the velocity of A is x `xx` 10m/s when B loses contact with floor, find x.

Two bodies whose masses are m_1 = 50 kg and m_2 = 150kg are tied by a light string and are placed on a frictionless horizontal . When m 1 is pulled by a force F = 100 N, find the acceleration produced in the bodies and the tension in the string .

In the arrangement shown in the figure all surfaces are frictionless, the masses of the block are m_1 = 20kg and m_2 = 30kg. The accelerations of masses m_1 and m_2 will be if F = 180N.
