Scientists launch a rocket, and they monitor its acceleration and the force exerted by its engines. as the rocket gets higher, the monitors show that the acceleration of the rocket is increasing but the force exerted stays the same. how do newton’s laws explain why the scientists could expect this to happen

a) the total force stays the same, but the action force is increasing as the reaction decreases.
b) the mass of the rocket decreases as fuel is burned, so the acceleration increases.
c) the inertia of the rocket increases, which reduces the force needed to change its speed.
d) the reaction force is increasing as fuel is burned, which causes a greater acceleration.

The correct answer is B.

Explanation:

Newton's first law states that " for an every action, there is an equal and an opposite reaction".

Newton's second law states that the force exerted on an object is directly proportional to the object's acceleration.

The force exerted stays the same which is exerted by the engine and the acceleration of the rocket is increasing in the given problem. It means that force is acting in the opposite direction due to its weight. The weight of the rocket is decreasing due to its burning fuel.

Therefore, the answer is "the mass of the rocket decreases as fuel is burned, so the acceleration increases".
