Question 83

An experimental nuclear fusion propulsion engine for a deep-space probe operates by converting a small fraction of reactant mass into energy. The total mass of the fuel in the reactor decreases at a constant rate of 1.62×10−4 kg hour−11.62 \times 10^{-4} \text{ kg hour}^{-1}1.62×10−4 kg hour−1.

What is the maximum power output of this propulsion engine?
