1. Boxing gloves are padded to lessen the force of a blow. The glove and face compress $7.50\mathrm{cm}$ during a blow in which the $7.00?\mathrm{kg}$ arm and glove are brought to rest from an initial speed of $10.0\mathrm{m}/\mathrm{s}$. (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 $v_0$ to be positive. Use the glove as the system for this part. Enter to 3 significant figures (e) Name the theorem or physics principle you used to calculate part (c). Newton's Second Law Work-Energy Theorem 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 $2\mathrm{cm}$. Consider the relative directions of $F$ and $d$ when determining the sign of the force. Consider the direction of $v_0$ to be positive. Enter to 3 significant figures $F_{\text{face }}=1$ N (Include sign)
