the european space agency launched a probe called rosetta in march 2004. in august 2014, rosetta reached its destination: a comet called 67p/churyumov-gerasimenko. rosetta is the first spacecraft to rendezvous with a comet. it contained a lander craft, called philae. the rosetta has a launch mass on earth of 3000 kilograms [kg] and the philae has a launch mass of 220 pound-mass [lbm lb m ]. in order to escape earth’s gravity, the combined spacecraft must accelerate at a rate of 25,000 miles per hour squared [mi/h2]. how much thrust, in units of newtons [n], must the engines provide to reach this acceleration?
