1. three forces act on a 5kg mass. the forces are 20n north, 30n west, 45n east. what is the magnitude and direction of the acceleration?
- how do I set this up? i am kinda lost on thsi one.
2. what is the gravitational force between a 100 kg object and a 200kg object if centers of mass are 10m apart. g= 6x10^-11 N m^2//kg^2
- this one too.. i don't know how i set this up.
3. describe the forces in terms of Newton's 3rd law that propel a rocket?
- what is this mean? i know Newton's 3rd law is for every action there is an equal and opposite reaction but what is this question asking?
4. under a balanced force there A) no change in translational motion B) No rotational motion C) no inertia D) all of above
- I am guessing it's C?
Any help would be greatly appreciated. It's not like I didn't try. None of this problems were done in class and I can't find similar examples either. :(
