Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

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).
