Quizplus · Accepted Answer

The force exerted by a punch is not just dependent on the strength of the person but also on the resistance offered by the object being punched. Tissue paper, due to its low resistance and inability to absorb much force before tearing, would not be able to withstand a force of 50 N from a punch without breaking. Therefore, the heavyweight champion cannot exert a force of 50 N on a piece of tissue paper held in midair without it tearing.
