Blockes A and B are resting on a smooth horizontal surface given equal speeds of `2ms^(-1)` in opposite sense as shown in the figure.

At t=0, the position of blocks are shown, then the coordinates of center of mass t=3s will be

A block is kept on a rough horizontal surface. A variable horizontal force is acting on the block as shown in the figure. At t=0 , block is at rest. Kinectic energy of block at t=5 sec will be (g=10m//s^(2))

A 15kg block is initially moving along a smooth horizontal surface with a speed of v=4m//s to the left. It is acted by a force F , which varies in the manner shown. Determine the velocity of the block at t=15 seconds.

A long block A is at rest on a smooth horizontal surface. A small block B whose mass is half of mass of A is placed on A at one end and is given an initial velocity u as shown in figure. The coefficient of friction between the blocks is mu .

A block of mass 10 kg is moving on a rough horizontal surface as shown in figure. At t=0 , velocity of block is 10 m/s towards left and a constant force F= 10 N acts horizontally towards right. Acceleration of the block at t=3s is ( g= 10 m s^(-2) )

A block of mass m moving with a velocity v_(0) on a smooth horizontal surface strikes and compresses a spring ofstiffuess k till mass coines to rest as shown in the figure. This phenomenon is observed by two observers : (a) Standing on the horizontal surface (b) standing on the block To an observer B, when the block is compressing the spring :
