Answer
46.7 MeV.
Work Step by Step
Calculate the Q-value, using data from Appendix B. We use atomic masses.
$$Q=\left( m_{d}+m(^{13}_{6}C)-m(^{14}_{7}N)-m_{n} \right)c^2$$
$$ =\left(2.014102u+13.003355u-14.003074u-1.008665u\right)c^2\left( \frac{931.49MeV/c^2}{u}\right)$$
$$=5.326MeV$$
The total KE of the products is the Q-value plus the KE brought in by the incoming deuteron: 5.326MeV + 41.4 MeV = 46.7 MeV.
