A block A of mass m=5kg is attached with a spring having force constant K=2000N/m. The other end of the spring is fixed to a rough plane ,
A block of mass m is connected rigidly with a smooth wedge (plank) by a light spring of stiffness k. If the wedge is moved with constant velocity v0 ,

A block A of mass m=5kg is attached with a spring having force constant K=2000N/m. The other end of the spring is fixed to a rough plane, inclined at 37 with horizontal and having coefficient of friction m=0.25. Block A is gently placed on the plane such that the spring has no tension. Then block A is released slowly. Calculate elongation of the spring when equilibrium is achieved. Now an inextensible thread is connected with block A and passes below pulley C and over pulley D, as shown in figure. Other end of the thread is connected with another block B of mass 3kg. Block B is resting over a table and thread is loose. If the table collapse suddenly and B falls freely through 80/9cm, the thread becomes taut, calculate combined speed of blocks at that instant, and maximum elongation of spring in the process of motion. (g=10m/s^2).

Two identical blocks A and B, each of mass m=2 kg are connected to the ends of an ideal spring having force constant k=1000 N/m . System of these blocks and spring is placed on a rough floor. Coefficient of friction between blocks and floor is μ=0.5. Block B is pressed towards left so that spring gets compressed.
