A bullet is accelerated down the barrel of a gun by hot gases produced in the combustion of gun powder. What is the average forc
elena-14-01-66 [18.8K]

Answer:4.259 kN

Explanation:

Given

mass of bullet m=0.02 kg

final velocity of bullet v=575 m/s

time taken =2.7 ms\approx 2.7\times 10^{-3} s

We know

Impulse=F_{avg}\cdot t=change\ in\ momentum

thus

Initial Momentum(P_i)=m\times 0

Final Momentum(P_f)=m\times v=0.02\times 575

P_f=11.5 kg-m/s

F_{avg}\times 2.7\times 10^{-3}=P_f-P_i=11.5

F_{avg}=4.259\times 10^3

F_{avg}=4.259 kN
