Need Help ！！！！！！！！

The figures show free-body diagrams (FBD) for an object of mass m. Write the x-y components of Newtons second law. Write your equations in term of the magnitudes of the forces F,F... and any angles defined in the diagram. One equation is shown to illustrate the procedure. 1. F1 民 3 F2 F2 mag max = may = F1-F2 ma,

2. It is good practice to draw an acceleration diagram (i.e. a diagram with the acceleration vector) next to the FBD. Then you can read the equations directly off of the diagrams. For example, consider F1 al F3 How does this modify your equations from the first example above?

  • Three forces of magnitudes F1=4.0N, F2=6.0N, and F3=8.0N are applied to a block of mass m=2.0kg

    Three forces of magnitudes F1=4.0N, F2=6.0N, and F3=8.0N are applied to a block of mass m=2.0kg, initially at rest, at angles shown on the diagram. (Figure 1)In this problem, you will determine the resultant (net) force by combining the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive).Part ACalculate the magnitude of the resultant force \(\vec{F}_{\mathrm{r}}=\vec{F}_{1}+\vec{F}_{2}+\vec{F}_{3}\) acting on the block.Part BWhat angle does \(\vec{F}_{\mathrm{r}}\) make with the positive \(x\)...
