Two identical blocks A and B of mass m joined together with a massless spring as shown in figure are placed on a smooth surface. If the block A moves with an acceleration `a_0`, then the acceleration of the block B is

Two masses A and B, each of mass M are fixed together by a massless spring. A force acts on the mass B as shown in figure. If the mass A starts moving away from mass B with acceleration 'a', then the acceleration of mass B wil be :-

Two blocks A and B of masses m and M are attached with ideal string and pulley, and placed on smooth horizontal surface. Force F is applied horizontally as shown in figure. Find the ratio of the acceleration of A to that of B.

Four blocks each of mass M connected by a massless strings are pulled by a force F on a smooth horizontal surface, as shown in figure.

Two blocks of masses m_(1) and m_(2) are connected by a massless spring and placed on smooth surface. The spring initially stretched and released. Then :

Two blocks of masses m_1 and m_2 are connected as shown in the figure. The acceleration of the block m_2 is :

If the blocks A and B are moving towards each other with accelerations a and b shown in fig. find the net acceleration of block C.

Two blocks A and B are arranged as shown in figure.The pulleys are light and frictionless.The strings are light and inextensible.If the acceleration of the block B is 3m/s^(2) ,then the acceleration of the block A is __________ m/s^(2)
