The moon has mass M and radius R.A small object is dropped from a distance of 3R from the moon's center. The object's impact speed when it strikes the surface of the moon is equal to sqrt(kGM//R) for k= |

Answer» `1/3` `K_(0)+U_(0)=K_(f)+U_(f)` `0-G(Mm)/(3R)=(1)/(2)mv_(f)^(2)-G(Mm)/(R)` `(1)/(2)mv_(f)^(2)=G(2MM)/(3R)` `v_(f)=sqrt(((4)/(3)GM)/(R))`. |
