The excited K* meson has a rest mass of 1.5828E-27 kg/ a What is the rest amss energy in joules? 1.43E-10 b What is this energy in MeVs? 893.75 here's where i need help c Now these K* are accelerated to a speed of 2.97E8 m/sec. What is the relatavistic mass of these K* in kg and MeV/c squared so far i have 1.5828E-27/radical(1-.99csquared)=1.12E-26 do I convert into MeV's and divide by 3E8squared? so 6282/3E8squared =6.98E-14 MeV/c squared d What is the relatavistic momentum of these K* in kgm/sec and in MeV/c?
