Question

If a spacecraft that seems to be motionless in deep space is given some type of quick push, what will happen?

A. The spacecraft will not move because it only works on earth.
B. The spacecraft will move and will not stop until it is stopped by an equal or opposite force.
C. The spacecraft will not move due to air resistance.
D. The spacecraft will move and then slowly come to a stop on its own.

Answer 1

the answer i believe is B

Answer 2

Answer:

B. The spacecraft will move and will not stop until it is stopped by an equal or opposite force.

Explanation:

From the first law of motion (given by Newton), a body continues to be in state of rest or motion, unless and until an unbalanced external force acts on it. This is also known as law of inertia.

So, according to this law, the spacecraft which is motionless would move when a push is given to it. It will now keep on moving until an equal and opposite force acts on it and stops it.

Thus, option B is correct.
