If a force of 60N is applied on the upper block will the two blocks move together with an acceleration of `4 m/s^2`. If not, find their acceleration.

The force applied on a stationary body varies directly with the acceleration with which it starts to move. If a force of 10 N is applied on a stationary body, it starts to move with an acceleration of 2 m/ sec^(2) . Find the force (in N) to be applied on the body at which starts to move with an acceleration of 4 m/ sec^(2) .

If block B moves towards right with acceleration b, find the net acceleration of block A.

A block of mass 2.0 kg is pushed down an inclined plane of inclination 37^0 with a force of 20N cting parallelto the incline. It is found tht the block moves on the incline with an acceleration of 10 m/s^2 . If the blcok started from rest, find the work done a. by the applied force in the first second b. by the weight of the block in the first second and c. by the frictional force acting on the block in the first second. Take g=10 m/s^2 .

A body of mass 2 kg is placed in a rough surface. When a force of 60 N is applied on it, it starts moving with an acceleration of 15m//s^2 . Find the friction force acting on it.

Find the acceleration of block B realtive to the ground if the block A moves to the left with an acceleration a_(0) .

The maximum value of F which can be applied on the system shown in figure so that both blocks move together with same acceleration is

Two blocks of mass 2 kg and 4 kg are kept in contact with each other on a smooth horizontal surface. A horizontal force of 12 N is applied on the first block due to which they move with certain constant acceleration. Calculate the force between the blocks.

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.
