find the power of a machine gun that can fire 240 bullets per minute each weighing in 50 gram with a velocity of 100 metre per second |

Answer» (mv^2)/2 is KE, so each BULLET has .05x100x100 / 2 = 5000J of kinetic ENERGY. 240 PER minute is 6 per second, so the power of the gun is 30,000W. 30kW is equivalent to about 40hp, so about the ENGINE power NEEDED to maintain a typical small car at highwayish speed on a flat road.Explanation:Mark as brainly |
