A man standing on very slick ice fires a rifle horizontally. The mass of the man together with the rifle is 70 kg , and the mass of the bullet is 10 g

If the bullet leaves the muzzle at a speed of 500 m/s, what is the final speed of the man?

  2. Conservation of momentum problem

    since system is a rest before firing

    0 = m1*v1 + m2*v2

    everything is given in problem besides v1

    So solve for v1
