Quizplus · Accepted Answer

The escape velocity formula is V=sqrt((2GM)/r), where G is the gravitational constant, M is the mass of the celestial body, and r is the distance from the center of the body. Plugging in the values, we get V=sqrt((2*(6.67*10^-11)*(7.2*10^22))/(1738000))=2.38 km/s. Rounded to the nearest tenth, the answer is 2.3 km/s, which is choice C.
