This system consists of a marble rolling down a ramp. assume the mass of the marble is 5.0 g. decide what would be needed to measure or determine the other quantities to calculate gravitational potential energy and kinetic energy. solve the equation for the speed of the marble at the bottom of the ramp and compare it to the experimentally measured value.

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?
