When calibrating a set of scales, we obtain a measurement value for the mass of a standard weight that is 0.296 kg greater than the nominal mass. Thus we conclude that the error of the scales is 59.2%. How many kilogrammes was the mass of the weight used in the calibration?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
