Please help with practice problems.

Vectors a. We have two forces F1 and F2, having magnitudes of 5N and 8N. What is the maximum and minimum possible resultant force (you're free to play around with the directions of F1 and F2) b. Arrange tw-o Vectors with magnitudes of 3 and 4 so that the resultant has a magnitude of 5. Draw the orientation of the vectors and mark the known angles (you must mention at least one angle) Spring Constant Find the SI Unit of the Spring Constant (k) using the equation F = kx Where F is the force andx is the deformation (elongation or compression) in the spring's length
