Question

A bullet of mass50gmis fired from a gunof mass 6kg with a velocity of 400m/s. Calculate the recoil velocity of the gun .

Answer 1

Answer:

v' = - 33.33 m/s ( -ve sign due to motion of gun opposite to bullet)

Explanation:

mass of bullet = m = 50 g = 0.5 kg

mass of gun = M =  6 kg

v = 400 m/s

v' = - m / M v

v' = - 0.5 / 6 x 400

v' = - 33.33 m/s ( -ve sign due to motion of gun opposite to bullet)
