Turbo-Charged Engine Versus Standard Engine In tests conducted by Auto Test Magazine on two identical models of the Phoenix Elite-one equipped with a standard engine and the other with a turbo-charger-it was found that the acceleration of the former is given by a = f(t) = 6 + 0.8t (0 sts 12) ft/sec/sec, t sec after starting from rest at full throttle, whereas the acceleration of the latter is given by a = g(t) = 6 + 1.2t + 0.03t2 (0 sts 12) ft/sec/sec. How much faster is the turbo-charged model moving than the model with the standard engine at the end of a 7-sec test run at full throttle? ft/sec
