The excited K* meson has a rest mass of 1.5828E-27 kg/(adsbygoogle = window.adsbygoogle || []).push({});

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?
