Aspacecraft left earth to collect soil samples from mars. which statement is true about the strength of earth’s gravity on the moving spacecraft? a. it decreases b. it increases c. it remains the same d. it doesn't affect the space craft

According to Newton's law of Gravitation, the force exerted between two bodies of masses and  and separated by a distance  is equal to the product of their masses and inversely proportional to the square of the distance:

Where is the gravitational constant

This means that the gravity force decreases when the distance between these two bodies increases.

So, in this particular case of the spacecraft, as it moves away from the Earth, the Earth's gravity force exerted on the spacecraft will decrease.

Therefore, the correct option is A.

answer; ///i believe that the correct answer is (carbon); good luck

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
