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 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 40m. The coefficient of sliding friction of the rough surface is ( g = 9.8 ms^(_2))

A block of mass m is placed at rest on a smooth wedge of mass M placed at rest on a smooth horizontal surface. As the system is released

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 bullet of mass 10g travels horizontally with speed 100m//s and is absorbed by a wooden block of mass 900 g suspended by a string. Find the vertical height through which the block rises. Given g=10m//s^(2)

A bullet fired horizontally with a speed of 400m/sec. It strikes a wooden block of mass 5kg initially at rest placed on a horizontal floor as shown in the figure.It emerges with a speed of 200m/sec and the block slides a distance 20cm before coming to rest.Find the coefficient of friction between block and the surface.Mass of bullet is 20g . (take g=10 m/s^(2) )

The 4 kg sphere form rest when theta = 60^(@) strikes a block mass of 5 kg placed on a rough horizontal plane and comes to rest after collision. The 5 kg block comes to rest after moving a distance of 0.8m . Find mu of ground & block & coefficient of restituation e.

A bullet of mass 10g 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. Also, Calculate the magnitude of the force exerted by the wooden block on the bullet,
