P5_10 A Dizzying Demonstration of Cartographical Centrality

Ben Rayson, Mark Sharman, George Knott, David Molloy


This paper aims to determine the angular velocity required of a earth-mass globe, situated at the center of the earth and spinning in the same orientation as the earth, to slow the earth's rotation by one hour. This new 25 hour day would necessitate an angular velocity of $\omega_g=7.679\times10^8$ rads/s. An explorer spinning the globe along the equator would need to move their hand at a tangential velocity of $2.34\times10^8$ ms\textsuperscript{-1}.
