Question

A gun of mass 1 Kg fires a bullet of mass 10g with a speed of 100 m/s. What is the recoil velocity of the gun?

Answer 1

Answer:

$by \: the \: theory \: of \: conservation \: of \: momentum \\ = )momentum \: of \: gun \: = momentum \: of \: bullet \\ = )mass \: of \: gun \times velocity \: of \: gun = mass \: of \: bullet \times velocity \: of \: bullet \\ = )1 \times v = 0.01 \times 100 \\ = )v = 1m. {sec}^{ - 1}$

Hence The Recoil Velocity of gun is 1m/sec
