Question

a spacecraft that seems to be motionless in deep space is given some type of quick push. which statement describes what will happen? hint: use the images to help you. a. the spacecraft will remain still because it only works on earth. b. the spacecraft will remain still due to air resistance. c. the spacecraft will move and then slowly come to a stop on its own. d. the spacecraft will move and will not stop until it is stopped by an equal and opposite force.

Explanation:

Step1: Recall Newton's first law

In deep - space, there is no air resistance. An object at rest will stay at rest and an object in motion will stay in motion with a constant velocity unless acted upon by an external force.

Step2: Analyze the spacecraft situation

The spacecraft is given a quick push, which is an external force. After the push, in the absence of other forces (no air resistance in deep - space), it will continue to move with a constant velocity until another force acts on it to stop it.

Answer:

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