    hello could anyone tell me why the total mass of the three particles after this event is greater than the mass of the two particles before?

    K− + P = K0+ K+ + omega minus
    (negative kaon+proton= neutral kaon+positive kaon+omega minus)

    the markscheme says the kinetic energy of the negative kaon is responsible. :s

    Mass is not always conserved, but mass-energy is. In order for the K- and P to combine they must be travelling at high speed, hence have a large kinetic energy. Some of this kinetic energy is converted into mass, leaving you with a greater total mass of reactants which also have less kinetic energy.
