Mass of one neutron = 1.67*10^-27 kg
velocity = 10^8 m/s
mass of other neutron = 1.67*10^-27 kg
velocity = 0

total mass, m = 3.34*10^-27 kg
final velocity = v

conserving momentum,
m1v1+m2v2 = mv
⇒ 1.67*10^-27 × 10^8 + 1.67*10^-27 × 0 = 3.34*10^-27 * v
⇒ v = 1.67*10^-27 × 10^8 / 3.34*10^-27
⇒ v = 10^8 / 2
⇒ v = 5×10^7 m/s
