\#4 A shell moving with a velocity of known components $$\mathrm{v}_{\mathrm{x}}, \mathrm{v}_{\mathrm{y}}$$, and $$\mathrm{v}_{\mathrm{z}}$$ explodes into three fragments of masses $$\mathrm{m}_{1}, \mathrm{~m}_{2}$$, and $$\mathrm{m}_{3}$$ at point $$\mathrm{A}_{0}$$ at a distance $$\mathrm{d}$$ from a vertical wall. Derive expressions for the speeds of the three fragment immediately after the explosion, knowing the coordinates $$\mathrm{x}_{\mathrm{i}}$$, and $$\mathrm{y}_{\mathrm{i}}$$ of the points $$\mathrm{A}_{\mathrm{i}}(\mathrm{i}=1,2,3)$$ where the fragments hit the wall. With the following numerical values compute the 3 velocities: A1 $$(-5 \mathrm{~m}, 0) ; \mathrm{A} 2(12 \mathrm{~m} ; 6 \mathrm{~m}) ; \mathrm{A} 3(0$$ $$\mathrm{m} ;-9 \mathrm{~m}) ; \mathrm{d}=12 \mathrm{~m} ; \mathrm{m}_{1}=5 \mathrm{~kg} ; \mathrm{m}_{2}=4 \mathrm{~kg} ; \mathrm{m}_{3}=3 \mathrm{~kg} ; \mathrm{v}_{\mathrm{x}}=40 \mathrm{~m} / \mathrm{s} ; \mathrm{v}_{\mathrm{y}}=-30 \mathrm{~m} / \mathrm{s} ; \mathrm{v}_{\mathrm{z}}=-1200$$
