A bullet of mass 0.02 kg travelling horizontally with velocity 250 `ms^(-1)`strikes a block of wood of mass 0.23 kg which rests on a rough horizontal surface. After the impact, the block and bullet move together and come to rest after travelling a distance of 40 m. The coefficient of sliding friction of the rough surface is `(g = 9.8 ms^(2))`

A bullet of mass 10 g travelling horizontally with a velocity of 300 m/s strikes a block of wood of mass 290 g which rests on a rough horizontal floor. After impact the block and the bullet move together and come to rest when the block has travelled a distance of 15 m. The coefficient of friction between the block and the floor will be - (Duration of impact is very short)

A body is moving along a rough horizontal surface with an initial velocity 6m/s m If the body comes to rest after travelling 9 m , then the coefficient of sliding friction will be

A body is moving along a rough horizontal surface with an initial velocity 6m/s m If the body comes to rest after travelling 9 m , then the coefficient of sliding friction will be

A bullet of mass 10 g travelling horizontally with a velocity of 150 m s^-1 strikes a stationary wooden block and comes to rest in 0.03 s. Calculate the distance of penetration of the bullet into the block.

A bullet of mass 50 g moving horizontally with a velocity 210 ms^(-1) gets embedded in a block of mass 1 kg kept on a rough horizontal surface. If the coefficient of kinetic friction between the block and surface is 0.5. The block- bullet system will move a distance of "______" before coming to res t(Acceleration due to gravity =10 ms^(-2)).

A bullet of mass 50 g moving horizontally with a velocity 210 ms^(-1) gets embedded in a block of mass 1 kg kept on a rough horizontal surface. If the coefficient of kinetic friction between the block and surface is 0.5. The block- bullet system will move a distance of "______" before coming to res t(Acceleration due to gravity =10 ms^(-2)).

A block slides with a velocity of 10 m/s on a rough horizontal surface. It comes to rest after covering a distance of 50 metre. If g is 10m//s^(2) , then the coefficient of dynamic friction between the block and the surface is

A bullet of mass 10 kg travelling horizontally with a velocity of 150 ms^(-1) strikes a stationary wooden block and come to rest in 0.03 s. Calculate the distance of penetration of the bullet into the block. Calculate the magnitude of force exerted by the wood in block in the bullet.
