A block of wood of mass `9.8 kg` is suspended by a string. A bullet of mass `200 gm` strikes horizontally with a velocity of `100 ms^(-1)` and gets embedded in it. The maximum height attained by the block is `(g = 10 ms^(-2))`.

A block of wood of mass 0.5 kg is suspended by means of a thin wire. A bullet of mass 0.020 kg is fired horizontally in the plane of the block with a velocity of 100ms^(-1) . If the bullet gets stuck inside the block, then calculate the height by which the system rises (g=9.8ms^(-2)) . Calculate the amount of heat produced in the block.

A block of wood of mass 10 kg is suspended with a long rope. A bullet of mass 50 g moving at 0.3 km *s^(-1) hits and gets embedded in that block . What will be the vertical rise of the block ? [g=980 cm *s^(-2) ]

A block of wood of mass 3M is suspended by a string of length (10)/(3) m . A bullet of mass M hits it with a certain velocity and gets embedded in it. The block and the bullet swing to one side till the string makes 120^@ with the initial position. the velocity of the bullet is (g=10 ms^(-2)) .

A bullet of mass m moving with velocity v strikes a block of mass M at rest and gets embedded into it. The kinetic energy of the composite block will be
