1. Boxing gloves are padded to lessen the force of a blow. 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. Think & Prepare 1. Make note of what's given and what's unknown. Relate known quantities to symbols. 2. Draw a labeled sketch if possible. 3. Identify the physics principle and approach. Write down relevant equations symbolically. Simplify if possible. 4. Insert numerical quantities to solve for unknowns. 5. Does the answer make sense? (a) Calculate the change in kinetic energy of the glove and arm. Enter to 3 significant figures AKE= Note: AKE = KE final-KE initial (b) Where does this energy go? J into doing work against the force exerted by the face against the glove into doing work against gravity into the potential energy of the face O into the potential energy of the glove and arm (c) Calculate the force exerted on the boxing glove by the opponent's face. Consider the relative directions of F and d when determining the sign of the force. Consider the direction of vo to be positive. Use the glove as the system for this part. glove Fface ď Enter to 3 significant figures Fglove N (Include sign) (d) Calculate the force exerted by the boxing glove on the opponent's face. Consider the relative directions of F and d when determining the sign of the force. Consider the direction of vo to be positive. Enter to 3 significant figures Fface = N (Include sign) (e) Name the theorem or physics principle you used to calculate part (c). O Newton's Second Law O Work-Energy Theorem O Superposition of forces (f) Calculate the force exerted by an identical blow on the face in the glory days when no gloves were used and the knuckles and face would compress only 2 cm.
