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
|F1 + F3| = |F2|
since the resultant force on the object is zero (constant speed, no acceleration, no force)
I don't Understand your answer
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
To find the magnitude of the combination of F2 and F3, we need to add the two forces together.
F2 is given as 7.8 N, and F3 is given as 8.3 N. Since both forces are acting in the same direction, we can simply add their magnitudes.
Magnitude of the combination of F2 and F3 = F2 + F3
Magnitude of the combination of F2 and F3 = 7.8 N + 8.3 N
Magnitude of the combination of F2 and F3 = 16.1 N
Therefore, the magnitude of the combination of F2 and F3 is 16.1 N.
