Question

4. The Voyager 1 and 2 spacecraft are now out beyond the orbit of Pluto. They have run out of fuel long ago but are still moving at a constant speed of 50,000 mph. According to Newton's laws of motion, the Voyagers will A) eventually slow down and come to a stop in the middle of interstellar space. B) continue to move in the same way forever, no matter what happens. C) continue to move in the same way until acted upon by a force. D) eventually slow down, turn around and come back to Earth.

Answer 1

Answer:

C

Explanation:

According to Newton's first law of motion, which states that a body will continue in its state of rest or uniform motion unless acted upon by an external force to change its state of rest or uniform motion. So, the Voyagers spacecraft will continue to move in the same way at the constant speed of 50,000 mph unless acted upon by a force.

Answer 2

Answer:

Option C is correct

Continue to move in the same way until acted upon by a force.

Explanation:

The newton's 1st law of motion states that:

"If an object is at rest then it will stay at rest or if an object is in motion then it remains in motion at the same speed as before unless acted upon by some unbalanced force"

The Voyager 1 and 2 spacecraft are still moving at a constant speed of 50,000 mph and they will keep on moving at this rate unless some unbalanced force acts on them.
