A machine gun fires 360 bullets per minute, with a velocity of 600 ~ms ⁻¹ . If the power of the gun is 5.4 kW , then mass of each bullet is

Step-by-step solution

Here, n = 360 60 =6 bullets s ⁻¹ Velocity, v =600 ~ms ⁻¹, ~m = ? Power of gun = Power of bullets 5.4 10^3= 1 2 ( ~nm ) v ^22 5400=6 m (600)^2 or aligned m & = 2 5400 6 600 600 ~kg & = 1 200 ~kg = 1000 200 ~g =5 ~g aligned
