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 = 11.9 cm with a 1,000 n load and x2 = 33.5 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)evaluate a and b in the empirical equationf=ax^b and
b) find the work needed to compress the spring 25.0 cm.
