In the figure, projectile particle 1 is an alpha particle and target particle 2 is an oxygen nucleus. The alpha particle is scattered at angle \( \theta_{1}=63.1^{\circ} \) and the oxygen nucleus recoils with speed \( 1.40 \times 10^{5} \mathrm{~m} / \mathrm{s} \) and at angle \( \theta_{2}=52.0^{\circ} \). In atomic mass units, the mass of the alpha particle is \( 4.00 \mathrm{u} \) and the mass of the oxygen nucleus is \( 16.0 \mathrm{u} \). What are the (a) final and (b) initial speeds of the alpha particle? (a) Number Units (b) Number Units eTexthnnk and Media
