A toy gun uses a spring of spring constant 1000 N/m . If spring is compressed by an amount 10 cm before fire then how high can be bullet be fired if mass of each bullet is 10 g .

A bullet of mass m is fired from a gun of mass M. The recoiling gun compresses a spring of force constant k by a distance d. Then the velocity of the bullet is

A block of mass M lying on a smooth· horizontal surface is rigidly attached ·to a light horizontal ·spring of spring constant k. The other end of the spring is rigidly connected to a fixed wall. A stationary gun fires ·bullets of mass m each in horizontal direction with speed upsilon_(0) one after other. The bullets hit the block and get embedded to it. The first bullet hits the block at t=0, the second bullent hits at t=2pisqrt((M+m)/(k))+2pisqrt((M+2m)/(k)) and so on. The maximum comression in the spring after the n^(th) bullet hits is :

Three friends divided some bullets equally. After each of them shot 4 bullets, the total number of bullets remaining is equal to the bullets each had after division. Find the original number of bullets:

The hydrogen bomb uses the principle of ……………………… .
