Problem 14PE
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?

ANSWER:
Step 1 of 4
The mass of the hand, initial speed and final speed is given. The distance, over which the speed is changed is also given. We have to calculate the force for both hands with gloves on it and hands without gloves on it.
Then we have to discuss if the force exerted by the hands with gloves on it is sufficient enough to cause any damage.
