Question

A 20 kg gun fires a bullet of mass 20 g with a velocity of 400m/s. Find The action on the shoulder of the person per second by the gun in Newton
Find find the answer in Newton and if you get the correct answer I will mark you as brainliest​

Answer 1

$\green{Linear \:Momentum \:is \:conserved}$

$mass \: of \: gun ,\: Mg = 20 \: kg$

$mass \: of \: bullet ,\: Mb = 20 \: g$

$velocity \: of \: bullet ,\: Vb = 400ms {}^{ - 1}$

$recoil \: of \: gun, \: Vg = Vg$

$\large\green{Linear\: Momentum \:is \:conserved}$

$\large{Mg \times Vg + Mb + Vb = 0}$

$\large{20 \times Vg + \frac{20}{1000} \times 400 = 0}$

$\large{20 \times Vg + 8 = 0}$

$\large{20 \times Vg = - 8}$

$\large{Vg = \frac{ - 8}{20}}$

$\huge\red{\boxed{\pink{Vg = - 0.4 \: ms {}^{ - 1}}}}$
