You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 10-m-high hill, then descends 20 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.1 m and that a loaded car will have a maximum mass of 440 kg. For safety reasons, the spring constant should be 12% larger than the minimum needed for the car to just make it over the top. NOV 2 *** ▼ Part A What spring constant should you specify? Express your answer with the appropriate units. View Available Hint(s) k= O μA Value Submit Previous Answers MacBook Air Units tv S . I
