A particle at rest, with mass mo = 48 M, decays, emitting two others (M is a constant with a unit of mass). The first one has mass m1 = 2 M, its energy and linear momentum represented by E1 and P1: The second particle created has mass m2 = 10 M, its energy and linear momentum represented by E2 and P2-The four-momentum of the created particles can be written in the form: P; = [E/c , pi] e P2 = [E3/c , p2l. Calculate the energy of the first particle created and mark below the item corresponding to its value.
