You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 680.0 kg and was traveling eastward. car b weighs 510.0 kg and was traveling westward at 72.0 km/h. the cars locked bumpers and slid eastward with their wheels locked for 6.00 m before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. 1) how fast (in kilometer per hour) was car a traveling just before the collision? (express your answer to three significant figures.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponentâs 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?
