Two boats are anchored in the harbor, separated by a horizontal distance of 18 m.

The boats bob up and down as waves enter the harbor. When one boat is at its

highest point, the other is at its lowest point and there are no wave crests between

them. Each boat makes exactly 5 complete up-and-down cycles every 10.0 s. The

vertical distance between a boat's highest and lowest position is 2.6 m.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
