In Figure 9-22, projectile particle 1 is an alpha particle and target particle 2 is an oxygen nucleus. The alpha particle is scattered at angle θ1 = 62.0° and the oxygen nucleus recoils with speed 1.10 ✕ 105 m/s at angle θ2 = 49.0°. In atomic mass units, the mass of an alpha particle is 4.00 u and the mass of an oxygen nucleus is 16.0 u.

(a) Find the final speed of the alpha particle.

(b) Find the initial speed of the alpha particle.
