41. (a) We use the relativistic relationship between speed and momentum: pm v mv vc == γ 1 2 b g , which we solve for the speed v : v c pc mc =− F H G I K J + 1 1 1 2 2 . For an antiproton mc 2 = 938.3 MeV and pc = 1.19 GeV = 1190 MeV, so c + = 1 1 1190 938 3 1 0 785 2 MeV MeV . .. b g (b) For the negative pion mc 2 = 193.6 MeV, and pc is the same. Therefore, c + = 1 1 1190 1936 1 0993 2 MeV MeV . b g (c) Since the speed of the antiprotons is about 0.78 c but not over 0.79 c , an antiproton will
