A 50 kg archer, standing on frictionless ice, shoots a 200 g arrow at a speed of 100 m/s. What
is the recoil speed of the archer?

P = mv
P of arrow = P of archer
(mass of arrow )*(speed of arrow) = (mass of archer)*(speed of archer)
solve for the speed of archer

It seems to me that it would be 100m/s * 0.2 / 50
