You are right. How silly of me. Well, I got 1.9 km /m for my answer. Thanks for your help.

Well, I did solve it for km/s I got 1.05 km/s. vf2y=0.53sin52 vf2y=0.418km/s vf2x=0.933 km/s If you use the Pythagorean theorem you get 1.05km/s

Homework Statement A neutron of mass 1.7 X 10^-27 kg traveling at 2.2 km/s, hits a stationary helium nucleus of mass 6.6 X 10^-27 kg. After the collision, the velocity of the helium nucleus is 0.53 km/s at 52° to the original direction of motion of the neutron. Determine the final velocity of...
