The force 15 N pulls the lower block for 2m, find speed.

For the two blocks shown in the adjacent figure, an external force of 18N is applied on the lower block. Find the acceleratiion of the upper block.

n indentical blocks each of mass m are connected by means less strings and a pulling force F is applied on the first block. Find block . Find the tension in the string connecting k^("th") and ) (k+1)^("th") blocks. If another pulling force F is applied on the least block, find the tension in the same . String.

A force of 0.5 N is applied on upper block as shown in figure. The work done ( in joule ) by upper block on lower block for a displacement of 3 m is :

Find the work done by the force of friction on the smaller block by the bigger block during a displacement d of the system.

A block of mass 25 kg is kept on a horizontal plane. The block is pulled in a direction 30^(@) to the horizontal, and when the force is 100 N, the block start its motion. Find the coefficient on friction between the block and the plane.

consider the situastion of the previous problem. Suppose the block of mass m_1 is pulled by a constant force F_1 and the other block is pulled by a constant force F_2 . Find the maximum elongation that the spring will suffer.
