Asked by vedvd
Hannah has information about an object in circular orbit around Earth.
mEarth = 6.0 × 1024 kg
G = 6.67 × 10–11 StartFraction m Superscript 3 Baseline over kilograms times s Superscript 2 Baseline EndFraction.
rearth=6.0 x 106 m
Using the information given what does Hannah need in order to calculate the tangential speed of the orbiting object ?
the mass of the orbiting object
the distance of the orbiting object to Earth
the orbital period of Earth
the radius of Earth

The distance of the orbiting object to Earth.
Reason: for a circular orbit v = sqrt(G M_E / r) so you need M_E (given) and the orbital radius r (distance from Earth's center). The orbiting object's mass cancels out, and the orbital period isn't required (unless you instead use v = 2πr/T, in which case you'd still need r).
