A proton with initial kinetic energy (5.2 MeV) collides with an alpha particle (initially at rest). The collision is perfectly elastic and the proton travels off at an angle of 133o relative to its initial direction. What is the velocity of the alpha particle after the collision? Assume the alpha particle has four times the mass of a proton.
My teacher made this problem but I'm trying to solve it and I need final velocity to find the answer and its not given.
