One at your summer lunar space camp activities is to launch n 1170-kg rocket from the surface of the moon. you are a serious space camper and you launch a serious rocket: ii reaches an altitude of 211 km. what gain m gravitational potential memo does the launch accomplish? the mass and radios of the moon are 7.36 x 10^22 kg and 1740 km, respectively.

To solve this problem it is necessary to apply the concepts related to gravitational potential energy.

The change in gravitational potential energy is given by,

Where,

Here,

G = Gravitational Universal Constant

M = Mass of Earth

m = Mass of Object

R = Radius

Replacing we have that

Note that h is the height for this object. Then replacing with our values we have,

Therefore the gravitational potential  is

wvbbvvv

i don't know that i agree with that but what's the question ?
