The parabola above is a grph of speed as a function of time t for an object. which of the tollowing graphs best ropresents the magnitude f of the net force exerted on the object as a function of time t? (a) f (b) f tci a 100-newton weight is suspended by two cords as shown above. the tension in the slanted cont (a) 50n (b 1oon (c is 24.

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?
