You are an industrial engineer with a shipping company. as part of the package- handling system, a small box with mass 1.60 kg is placed against a light spring that is compressed 0.280 m. the spring has force constant 48.0 n/m . the spring and box are released from rest, and the box travels along a horizontal surface for which the coefficient of kinetic friction with the box is μk = 0.300. when the box has traveled 0.280 m and the spring has reached its equilibrium length, the box loses contact with the spring. (a) what is the speed of the box at the instant when it leaves the spring? (b) what is the maximum speed of the box during its motion?

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?
