Three forces are exerted on an object placed on a slope in the figure. The forces are measured in newtons (N).
1. Assuming that forces are vectors, what is the component of the net force F⃗ net=F⃗ 1+F⃗ 2+F⃗ 3 parallel to the slope?
2. What is the component of F⃗ net perpendicular to the slope?
3. What is the magnitude of F⃗ net?
4. What is the direction of F⃗ net?
