Astudent is swimming south applying a force of 256 n. the water exerts a westward force of 104 n. if the student has a mass of 95.3 kg, what is the acceleration of the student? hint: the weight of the student is balanced with the water buoyant force, therefore those are the only forces affecting the resultant force.

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?
