Imagine that Zapata was able to fly his machine far out into outer space. What do you predict would happen to Zapatas forward movement through outer space if the machine runs out of fuel?

B, the machine and passanger would continue moving forward indefinatly (forever) at a constant rate.

Explanation:

According to Newton's first law of physics, "an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force". In space there is no gravity to slow down the machine, therfore they would keep moving until something interfered.
