Boxing gloves are padded to lessen the force of a blow. a. Calculate the force (in N) exerted by a boxing glove on an opponent's face, if the glove and face compress 6.50 cm during a blow in which the 6.00 kg arm and glove are brought to rest from an initial speed of 10.0 m/s b. Calculate the force (in N) 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. (Assume the total mass of the arm remains 6.00 kg.) 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?

Helmholtz Free Energy

The Helmholtz free energy is a thermodynamic potential used to calculate the measure of useful work from a closed system. This system is kept at constant temperature and volume. German physicist Hermann Helmholtz introduced this concept in 1882.
