A bullet of mass 20 g has a n initial speed of `1ms^(-1)` just before it starts penetrating a mud wall of thichness 20cm. If the wall offers a mean resistance of `2.5xx10^(-2)N` the speed of the bullet after emerging from the other side of the wall is close to:
A bullet of mass 20 g has an initial speed of 1 ms^(-1) just before it starts penetrating a mud wall of thickness 20 cm. If the wall offers a mean resistance of 2.5 xx 10^(-2)N the speed of the bullet after emerging from the other side of the wall is close to:
A bullet of mass 20 g is moving with initial speed of 1ms^(-1) just before it starts penetrting a mud wall of thickness 20 cm. If the wall offers a mean resistance of 2.5xx10^(-2)N , the speed (in m/s) of the bullet after emerging from the other side of the wall is nearly equal to:
A bullet of mass 5 g travels with a speed of 500m/s. If it penetrates a fixed target which offers a constant resistive force of 1000N to the motion of the bullet, find (a) the initial kinetic energy of the bullet (b) the distance through which the bullet has penetrated.
A bullet of mass 0.06 kg moving with a speed of 90ms^(-1) enters a heavy wooden block and it stopped after a distance of 60 cm. What is the average resistive force exerted by the block on the bullet ?
A bullet of mass 0.04 kg moving with a speed of 90 ms^(-1) enters a heavy wooden block and is stooped after a distance of 60 cm . What is the average resistive force exerted by the block on the bullet ?
A bullet has a mass of 20 g and is moving with a speed of 1000 cms^(-1) . It can penetrate 10 cm of a given target before coming to rest. If the same target were only 6 cm thick, what will be the speed of the bullet when it comes out ?
