Chapter , Problem 71(choose chapter or problem)
In Fig. 9-21, projectile particle 1 is an alpha particle and target particle 2 is an oxygen nucleus. The alpha particle is scattered at angle u1 64.0# and the oxygen nucleus recoils with speed 1.20 $ 105 m/s and at angle u2 51.0#. 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?

QUESTION:
In Fig. 9-21, projectile particle 1 is an alpha particle and target particle 2 is an oxygen nucleus. The alpha particle is scattered at angle u1 64.0# and the oxygen nucleus recoils with speed 1.20 $ 105 m/s and at angle u2 51.0#. 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?
ANSWER:Step 1 of 3 a) The law of conservation of momentum in the Y-axis is given by, Given, Mass of the alpha particle, Mass of the oxygen nucleus, The scattering angle of alpha particle, The recoil angle of oxygen nucleus, Recoil speed of oxygen nucleus, So, That is, The final speed of the alpha particle is .
