Two bodies of unequal mass are moving in...

Two bodies of unequal mass are moving in the same direction with equal kinetic energy. The two bodies are brought to rest by applying retarding force of same magnitude. How would the distance moved by them before coming to rest compare ?

According to the work energy therorem,
Change in KE=Work done by the retarding force
KE of the body=Retarding force`xx` Displacement
As KE of the bodies and retarding forces applied on them are same, therefore, both bodies will travel equal distances before coming to rest.
