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 450 kg. For safety reasons, the spring constant should be 14% larger than the minimum needed for the car to just make it over the top. Part A What spring constant should you specify? Express your answer to two significant figures and include the appropriate units.
