A neutron of mass 1.7 X 10^-27 kg travelling 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 the neutron.
The Attempt at a Solution
I changed all the km/s to m/s since the answer is in m/s
Well, it does not matter what i get for the y component since the answer 1.9 m/s and 933 is just too high.
So, is the answer wrong or did i do something wrong.
