Force on a Space Vehicle

What is the magnitude of the net force on a 160-kilogram space vehicle traveling at a constant speed of 800 meters per second?

Choose the correct option:

(1) 0 N

(2) 1.60 × 10^2 N

(3) 8.00 × 10^2 N

(4) 1.28 × 10^5 N

Answer:

The 160-kilogram space vehicle moving at a constant speed in a straight line would have a net force of 0 N acting on it according to Newton's First Law of Motion.

Explanation:

The subject of this question is Physics, specifically dealing with the concept of Newton's First Law of Motion. This law states that an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the case of the space vehicle, it is moving at a constant speed in a straight line, which means that there is no change in velocity and therefore, no net force acting on it. Therefore, the correct answer to the question is (1) 0 N as the magnitude of the net force on the space vehicle is zero. This is because there are no unbalanced forces acting on the vehicle as it moves at a constant velocity.
