In order to progress forward, he may have tossed the coins backward.The law of conservation of momentum can be used to explain the aforementioned statement.The guy and the gold coins had zero initial motion since they were initially at rest.Due of action and response, the man travels forward when he throws the coins backward.In accordance with the principle of momentum conservation, if no external force results,Total final momentum = Total initial momentum&amp;nbsp;Total final momentum = 0&amp;nbsp;Final Momentum of man + Final Momentum of gold coins = 0&amp;nbsp;Final momentum of man = - Final momentum of gold coins&amp;nbsp;m1V1=−m2V2&amp;nbsp;Velocity of the man,&amp;nbsp;V1=−m2V2m1&amp;nbsp;It is clear that the man moves opposite to the gold coins.
