1. The problem statement, all variables and given/known data A stationary B nucleus decays into two alpha particles and a proton, and the speed of the proton is found to be 6.0x10^6 m/s. What is the magnitude and direction of the velocities of the alpha particles with respect to the proton? 2. Relevant equations Unnecessary 3. The attempt at a solution Velocity has been found... what would the direction be? I was thinking opposite of the proton because they both have a positive charge but there is TWO alpha particles instead of one so wouldn't they be deflected at some angle instead of directly in front or behind the proton?
