A helium atom collides elastically with an oxygen atom at rest. After the collision the He atom is moving with velocity of 6.6 10 6 m - at S an angle of 85 degrees relative to its initial direction. The oxygen atom is moving at an angle of -40.4 degrees. First find the speed of the oxygen atom and then find the speed of the He atom (you will need to look up the masses of the two types of atoms).
