machine fires 5 bullets per sec each of velocity 200m/sec. find power of the gun.

To find the power of the gun, we need to first calculate the kinetic energy of each bullet and then multiply it by the rate of fire (number of bullets fired per second). The formula for kinetic energy is:

Kinetic Energy = (1/2) * mass * velocity^2

In this case, we are given the velocity of the bullet (200 m/s), but we do not have the mass of the bullet. Without the mass of the bullet, we cannot calculate the kinetic energy or the power of the gun accurately.
