Three forces, F1 = 9.2 N, F2 = 7.8 N and F3 = 8.3 N are acting on a small box of mass 47.0 kg. If the box is moving in the direction of F2 at constant speed, what is the magnitude of the combination of F2 and F3
Answered by Damon
|F1 + F3| = |F2|
since the resultant force on the object is zero (constant speed, no acceleration, no force)

I don't Understand your answer
Answered by Damon
There is no net force on the object if it is moving at constant speed

Therefore if it is moving in the direction of F2
then the sum of the other two forces must be equal and opposite to F2
