1. An alpha particle moving at 3% of the speed of light collides elastically with a stationary aluminium nucleus (atomic number 13 and mass number 27). If the alpha particle bounces bak at 0.1% of the speed of light , what is the velocity of the aluminium nucleus after the collision ?
2. Explain why the slingshot orbit of a satellite passing near a planet and then flying away at a different angle as a result of the effect of the planet's gravity would be an elastic collision .
The first question I'm a little unsure with the masses to use , but it seems a straightforward momentum Q ? The second one I have an explanation but it's far too long winded for a line -maybe it's something simple ?
