Answer
5.4 MeV. We begin here:
Work Step by Step
We arrived at this result using the formula in problem 6.
We assumed $1=\Lambda^o$
$2=p$
$3=\pi^-$
And we put in the values of the rest mass energies.
$E_1$ is the rest mass energy of $1$, $E_2$ is the rest mass energy of $2$ and $E_3$ is the rest mass energy of $3$.
$K_2$ is the kinetic energy of $2$.
