(50\%) Problem 1: A 7.5-kg bowling ball moving at $9.25\mathrm{m}/\mathrm{s}$ collides with a $0.95?\mathrm{kg}$ bowling pin, which is scattered at an angle of $?=20.5^{?}$ from the initi direction of the bowling ball, with a speed of $11.7\mathrm{m}/\mathrm{s}$. 50\% Part (a) Calculate the direction, in degrees, of the final velocity of the bowling ball. This angle should be measured in the same way that $?$ is. ${?}_{\mathrm{b}}=19.64\times$ Attempts Remain
