Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
