A bullet of mass `m`m penetrates a thickness `h` of a fixed plate of mass `M`. If the plate was free to move, then the thickness penetrated will be

Choose the correct option: A bullet of mass m penetrates a thickness h of a fixed plate of mass M . If the plate was free to move, then the thickness penetrated will be

A shot of mass m penetrates a thickness t of a fixed plate of mass M.If M were free to move and the resistance supposed to be uniform, find the thickness penetrated.

A sharp knife of mass m=1//2 kg penetrates s=5 cm into fixed wooden block of mass M=5 kg when it falls from a height of h=2 m. How much will it penetrate when thrown horizontally with velocity v = 10 m//s ? How much will it penetrate if the block is free to move on smooth surface ?

Solve the following examples: (numerical problems) A bullet having a mass of 10 g and moving with a speed of 1.5 m/s penetrates a thick wooden plank of mass 90 g. The plank was initially at rest. The bullet gets embedded in the plank and both move together. Determine their velocity.

A bullet of mass m travelling horizontally with speed u strikes a wooden block of mass 'M' placed on a smooth horizontal plane. The penetration is assumed uniform and the bullet comes to rest after penetrating a distance 'd' into the block. Then choose the correct statement :

A bullet moving with a speed of 100 ms^1 can just penetrate two planks of equal thickness. Then, the number of such planks penetrated by the same bullet when the speed is doubled will be
