Suppose you have a spring as shown in the (unfortunately poor quality) image below. You measure the initial position of the bottom part of the spring when no mass is hung from it and define this to be 0.00 meters (note: the "unit" here are some number of meters). Next, you hang a mass, let's say 0.50 kg from the spring and you notice the spring stretches 0.30 meters. yi = 0 y1 = 1 [unit] :N: yf = 1 K 3 3 Determine the value of the spring constant of the spring. Give your answer in units of N/m, however do not include the units explicitly in your answer. If you include units, the answer will be counted wrong
