Question

A satellite moves in a circular orbit around
the Earth at a speed of 6.3 km/s.
Determine the satellite’s altitude above
the surface of the Earth. Assume the
Earth is a homogeneous sphere of radius
6370 km and mass 5.98 × 1024 kg. The
value of the universal gravitational constant
is 6.67259 × 10−11 N · m2/kg2.
Answer in units of km

Answer 1

you can start from thinking that the gravitational force equals centrifugal force.

Then you can solve distance from there.

Answer 2

centrifugal force?

Answer 3

\[F=\frac{ m*v ^{2} }{ r } \]

Answer 4

I got 3.67953*10^6 but I think its wrong

Answer 5

you got the right answer except unit.. check the unit.

Answer 6

Hmm how do I change the units?

Answer 7

what you got is unit in meter. If you turn it into km, you have to divide it by 1000.

Answer 8

THANK YOU

Answer 9

u r welcome !
