Rutherford fired a beam of alpha particles (helium nuclei) at a thin sheet of gold. An alpha particle was observed to be deflected by 90.0°; its speed was unchanged. The alpha particles used in the experiment had an initial speed of 2.2 ✕ 107 m/s and a mass of  6.7 ✕ 10−27 kg.  Assume the alpha particle collided with a gold nucleus that was initially at rest. Find the speed of the nucleus after the collision.
