The Eurasian plate, has a mass of 2.5*10^22kg and travels over the Earth's interior at 7 mm yr^-1. Express this speed in m s^-1(note there are 3.15*10^7 seconds in a year).
Using the equation for kinetic energy Ek=1/2mv^2 (where m is mass and v is speed) calculate the kinetic energy of the Eurasian plate, give the final answer to the nearest order of magnitude.
