Question

The diameter of a car's suspension spring decreases uniformly. The force exerted by the spring is given by F = axb. Consider a suspension spring that compresses x1 = 12.2 cm with a 1,000 N load and x2 = 32.0 cm with a 5,000 N load. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) (a) Find the constants a (in units of N/mb) and b. a = N/mb b = (b) Calculate the work (in J) needed to compress the spring 26.0 cm. (Assume the spring is not initially compressed.) J
