1. The problem statement, all variables and given/known data 1) When a swimmer dives into water just before piercing himself into water, he stretches himself. Why? 2)In a tug of war if the parties on both ends of the rope apply apply equal and opposite forces on each other then how can one party win? 3. The attempt at a solution 1) I think, on stretching the body the resistance force by water on swimmer would decrease. But I cannot figure out the reason for it??? Please help me. 2)I simply cannot figure out the reason. I drew the FBD's the forces on the rope cancel out. the tension and the friction on each party is the same. But then how can a team win?
