Expert Answer:

A bike and a car brought to rest by applying same retarding force. If both travel same distance, during the journey till they come to zero, the velocity of both will change but mass will not change. As bike and car brought to rest their velocity will get decrease and reach to zero as they stop. As velocity decreses ultimately their kinetic energy also will get decrease and reach to zero.
