Ethanol blended with gasoline can be used to power a​ "flex-fueled" car. One particular blend that is gaining in popularity is​ E85, which is​ 85% ethanol and​ 15% gasoline. E85 is​ 80% cleaner burning than gasoline​ alone, and it reduces our dependency on foreign oil. But a​ flex-fueled car costs ​$ more than a conventional​ gasoline-fueled car.​ Additionally, E85 fuel gets ​% less miles per gallon than a conventional automobile. Consider a​ 100% gasoline-fueled car that averages miles per gallon. The​ E85-fueled car will average about miles per gallon. If either car will be driven miles before being traded​ in, how much will the E85 fuel have to cost​ (per gallon) to make the​ flex-fueled car as economically attractive as a conventional​ gasoline-fueled car? Gasoline costs ​$ per gallon. Work this problem without considering the time value of money.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
