Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! Part 4 A particle with mass M and charge + e and its antiparticle (same mass M, charge - e) are initially at rest, far from each other. They attract each other and move toward each other. (d) Now consider a specific case: a proton and an antiproton, each with an initial speed of 5.2 x 10' m/s when they are far apart. When these two particles collide, they react to form two new particles: a positive pion ( * , charge + e) and a negative pion (", charge -e). Each pion has a rest mass of 2.5 x 10-28 kg. These Part 1 pions have enough energy that they move away from each other. When these two pions have moved very far away from each other, how fast is each pion going, U? U = i m/s (a) Which of the diagrams below corre separation? Save for Later Attempts: 0 of 6 used Submit Answer Part 5 (e) When the pions are far apart, what is true of their speed? Save for Later Attempts: 0 of 6 used Submit Answer O Part 6 (f) As the pions move away from each other, the ratio of the absolute value of electric potential energy to U the final total kinetic energy K of the two pions ( changes. At some point, the potential energy becomes negligible compared to the final total kinetic energy K. K+U We can consider that the value of the ratio is about 0.01 when U
