In Figure projectile particle I is an alpha particle and target particle 2 is an oxygen nucleus.

Question:

In Figure projectile particle I is an alpha particle and target particle 2 is an oxygen nucleus. The alpha particle is scattered at angle θl = 64.0o and the oxygen nucleus recoils with speed 1.20 x 105 m/s and at angle θl = 51.0o. In atomic mass units, the mass of the alpha particle is 4.00 u and the mass of the oxygen nucleus is 16.0 u. What are the

(a) Final and

(b) Initial speeds of the alpha particle?
