Atrain starts from rest and accelerates uniformly until it has traveled 2.1 km and acquired a forward velocity of the train then moves at a constant velocity of for 400 s. the train then slows down uniformly at until it is brought to a halt. the distance traveled by the train while slowing down is closest to a train starts from rest and accelerates uniformly until it has traveled 2.1 km and acquired a forward velocity of the train then moves at a constant velocity of for 400 s. the train then slows down uniformly at until it is brought to a halt. the distance traveled by the train while slowing down is closest to 3.8 km. 4.2 km. 3.6 km. 4.4 km. 4.0 km.

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?
