Find the sum of each set of forces acting at the same point in a straight line.
1. 355 N (right); 475 N (right); 245 N (left); 555 N (left)
2. 703 N (right); 829 N (left); 125 N (left); 484 N (left)
3. Forces of 225 N and 175 N act at the same point.
(a) What is the magnitude of the maximum net force the two forces can exert together?
(b) What is the magnitude of the minimum net force the two forces can exert together?
4. Three forces with magnitudes of 225 N, 175 N, and 125 N act at the same point.
(a) What is the magnitude of the maximum net force the three forces can exert together?
(b) What is the magnitude of the minimum net force the three forces can exert together?
