На какой высоте (в км) над поверхностью Земли ускорение свободного падения в 25 раз меньше, чем на земной поверхности? Радиус Земли 6400 км.

Ответы

Автор ответа: emosip24

g=(GM)/(R+h)^2

ускорение свободного падения на высоте h равно 10/25=0,4м/с^2

масса земли равна 6*10^24 кг

(R+h)^2= GM/g

h= 6397v
