## Homework Statement

An unstable particle with a mass equal to 3.34*10^-27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.987c and -0.868c. Find the masses of the fragments.

## Homework Equations

conservation of momentum: 0=(m1*0.987c)/sqrt(1-(0.987)^2-(m1*0.868c)/sqrt(1-(0.868)^2

conservation of total energy: 3.34*10^-27 kg=m1/sqrt(1-(0.987)^2+m2/sqrt(1-(0.868)^2

when I solve this for m1 or/and m2 it gives me the wrong result.

Solutions:

mfaster=2.51*10^-28 kg

mslower=8.82*10^-28 kg
