Aprojectile of mass 9.6 kg is launched from the ground with an initial velocity of 12.4 m/s at angle of 54° above the horizontal. at some time after its launch, an explosion splits the projectile into two pieces. one piece, of mass 6.5 kg, is observed at 1.42 seconds after the launch to be at a height of 5.9 m and at a horizontal distance of 13.6 m from the launch point. find the location of the second fragment at that same instant of time.

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?
