Solution: If we examine Figure 16.8, we see that we should be able to determine the answer
to part (1) from the right-going Hugoniot in the magnesium.
A right-going Hugoniot is described by Equation 16.26, but since the magnesium was not
initially moving we can use Equation 16.25, and to stay consistent with our diagram we
will say the particle velocity is u
1
for this case:
