This problem is actually Problem 17 in Chapter 4 of Physics, 9th edition, by Cutnell et al., from which the Italian textbook draws much...

The question text by itself is one thing, but it's the illustration (usually made by an artist) that strongly suggests a non-zero net...

You and me both. thank you for the clarification.

I appreciate your feedback. I’m a 16-year-old student in my third year of high school in Italy, so I’m still learning. I’m studying...

Not to overly-complicate the problem, but does it make a difference that the engine forces are not applied at the Center of Gravity...

I hadn’t thought about that. I just followed the information given in the exercise and calculated the resultant forces. Thank you for...

Perhaps call them ##a_1## and ##a_2##.

Oh, I understand now! Since the mass is the same in both cases, the acceleration is proportional to the resultant force. Therefore, a1 =...

In this case, when the two forces act in the same direction, the resultant force is 2F. When they are perpendicular, the resultant force...

Yes

I understand that force and acceleration are vectors, but I still don’t understand how to relate the two accelerations to find the final...

My attempt and thoughts I know that the two engines exert the same force and that the spacecraft starts from rest. First, I need to...
