The kinetic energy would be infinite at the speed of light. It is NOT (1/2)M V^2.
The ship would have to travel at a lower speed.
Perhaps the teacher is unaware of the Theory of Relativity. If so, he or she should not be teaching this subject.
Assume that the Starship Enterprise is moving through space at the speed of light. Calculate how much kinetic energy the ship has at this speed. The Enterprise has a mass of 1*10^6kg. Now imagine that Captain Kirk wants to bring the ship to a complete stop in a distance of 30km. What braking or stopping force would be required to accomplish this?
