12 kg-m, calculate the angular acceleration if the rod in the previous problem has a moment of inertia, i caused by these torques. 19. a 6n force and a 15 n force act on an object. the moment arm of the 6 n force is 0.4 m. if the 15 n 20. force provides 5 times the torque of the 6 n force, what is its moment arm?

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?

Of is j/kg·k. if a 2.6 kg of isk to k, is ?
