Introduction to P Block

Two blocks are connected over a massless pulley as shown in figure. The mass of block A is 10 kg and the coefficient of kinetic friction is 0.2 Block A sliders down the incline at constant speed. The mass of block B in kg is

Figure shows two small blocks placed on smooth horizontal surface. They start moving from the same line with forces 2F and F respectively acting on the blocks. Their momenta and kinetic energies at the instant of crossing the finishing line as shown in figure are P_(A), P_(B) and K_(A), K_(B) . Then choose the correct option.

The spring shown in figure is unstretched when a man starts pulling on the cord. The mass of the block is M . If the man exerts a constant force F , find (a) the amplitude and the time period of the motion of the block, (b) the energy stored in the spring when the block passes through the equilibrium position and (c) the kinetic energy of the block at this position.

A block P of mass m is placed on a smooth horizontal surface. A block Q of the same mass is placed over the block P and the coefficient of static friction between them is mu . A spring of spring constant K is attached to block Q. The blocks are displaced together to a distance A and released. The upper block oscillates without slipping over the lower block. The maximum frictional force between the block is:

Two blocks P and Q of masses 0.3 kg and 0.4 kg respectively are stuck to each other by some weak glue as shown in the figure. They hand together at the end of a spring with a spring constant "k = 200 N m"^(-1) . The block Q suddenly falls free due to failure of glue, then find the maximum kinetic energy of the block P during subsequent motion (in mJ).

Acceleration of block A varies with time as shown in figure the value of coefficient of kinetic friction between block A and B is
