There is a thread for Lenny Conundrums.
I don't even know what a Lenny conundrum is. Why I've been avoiding that thread.
THE CURRENT LENNY CONUNDRUM
Assume the world of Neopia is a spherical planet with a diameter of 1600 km with a uniform density of 5200 kilograms per cubic metre.
If the Virtupets Space Station is in a circular orbit 630 km above the surface of Neopia, what is its orbital velocity in metres per second? Please round up to the nearest whole number.
any one know the awnser ?
