Hey guys, I'm a beginner physics student and I don't really know how to answer this question: I have a spring, ruler,3 known masses, and 1 unknown mass.How would I find the unknown mass using these materials? Is it possible to solve using Hooke's Law? It would be very helpful if you guys can provide some equations or include any diagrams. Also how would I derive the needed equations from a graph? Thanks Alot!
