A bullet enters in a piece of wood with velocity `v_(0)` and the resistive force acting on the bullet in the vood is proportional to `v^((1)/(3))`. If the total distance travelled by the bullet is proportional to `(v_(0))^(beta)`, then the value of `beta` is

A gun fires N bullets per second, each of mass m with velocity v. The force exerted by the bullets on the gun is :

A bullet enters a wooden block with velocity 120 m/s. The bullet travels 1.5 s in the block before its velocity reduces to zero due to resistance force which is proportional to the square root of the velocity. The distance travelled by the bullet in the wooden block is

A gun is firing bullets with velocity v_0 by rotating it through 360^@ in the horizontal plane. The maximum area covered by the bullets is

A bullet enters a block of wood with a velocity u. Its velocity decreases to v after going through a distance x inside. After covering a further distance y inside the bullet stops. Prove that (u)/(v) =sqrt((y+x)/(y)) .

Having gone through a plank of thickness h, a bullet changed its velocity from v_(0) to v_(1) . Find the time of motion of the bullet on the plank, assuming the resistance force to be proportional to the square of the velocity.
