An existing levee has a top width of 10 feet, a top ele- vation of 10 feet above the base, and 3: 1 (horizontal: vertical) slopes on both sides. if the levee is to be raised to an ele- vation of 15 feet and must meet new standards requiring a 12-foot top width, how much additional land space (in ft2) will be needed for the base of the levee per mile of levee length? assume side slopes remain 3: 1. show all work, and support your answer with appropriate drawings and schematics

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?
