    What is the recoil speed of a rifle after firing a bullet at 124m/s?

    Physics question, velocity... Homework Statement A rifle with a weight 19N fires a .0067kg bullet with a speed of 124m/s. The acceleration of gravity is 9.81 m/s2. Find the recoil speed of the rifle. Answer in units of m/s. Homework Equations F=ma, F= m(change in velocity/change in...
