A black hockey puck of mass $m$ sliding across frictionless ice at speed $V_{?}$ collides with an otherwise identical white hockey puck initially at rest. After the collision the black puck moves at an angle ${?}_b$ to the right of its original direction, while the white puck moves at ${?}_{?}$ to the left of the incoming puck's original direction. a) Find the final speeds of the two pucks. $V_b=$ ? $V_b{V}_b$-? b) Calculate the final speeds if the black puck has mass $0.16\mathrm{kg}$ and initial speed $32\mathrm{m}/\mathrm{s},{?}_b=65^{?}$ and ${?}_{?}=25^{?}$.
