An atomic nucleus traveling with speed 5800 m/s collides elastically with a target particle, initially at rest, which has twice the mass of the first nucleus. The first ( moving) nucleus bounces off the target at an angle of 90° .At what angle does the target particle move after the collision? What is the final speed of the first nucleus ( the one that was initially moving)? What is the final speed of the target nucleus (the one that was initially at rest)?
