7. 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 (lb). 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?
