Two springs with spring constants k1 and k2are put together end-to-end. Let x1 be the amount by which thefirst spring is stretched relative to its equilibrium length, andsimilarly for x2. If the combined double spring is stretched by an amount b relative to its equilibrium length, then b = x1 + x2. Find the spring constant, K, of the combined spring in terms of k1 andk2.
Pick at least two sample cases and for each sample case include both a physical reason you'd expect fo to go up or down (think about how sound waves are squishing together or spreading apart) and a mathematical reason (like will picking a + in the..
