Question

A 10 g is short from the 5 kg gun with the velocity of 400 m/s .What is the speed of recoil of the gun.

Answer 1

$ASSALAMUALAIKUM$

GIVEN VALUES:-

mass of bullet = 10g = 0.01kg

mass of gun = M = 5kg

velocity of bullet = V = 400m/s
______________________________
SOLUTION :-

»By conservation of momentum

Mv=mV

5 X v=0.01*400

v = 4 / 5

v = 0.8m/s

ANSWER :- v = 0.8m/s
