A. The kinetic energy increases as its speed increases.
Explanation:
The kinetic energy of an object is energy possessed by an object by virtue of its motion.
Now, kinetic energy of a moving body is given by;
KE = 1/2 mv^2
Where;
m = mass of the body
v = velocity (speed) of the body
It follows that if the mass of the spaceship is constant, a sudden increase in speed leads to a corresponding increase in the kinetic energy of the spaceship in accordance with the relationship show above.
