Question

a bullet mass 50g is fired from a rifle of mass 4kg with an initial velocity of the rifle?​

Answer 1

Answer:

From a rifle of mass 4 kg, a bullet of mass 50 g is fired with an initial velocity of 35 m/s. Calculate the initial recoil velocity of the rifle. Initially, the rifle is at rest. The negative sign indicates that the rifle recoils backwards with a velocity of 0.4375 m/s.
