North America and Europe lie entirely north of the equator. Almost all of Asia, most of Africa, and a part of South America are above the equator. Not sure if South America counts as 'mostly' though. That's up to you.
When you are finding the kinetic energy, it is best to keep this formula in mind.
Ek = 1/2mv²
Where m is mass and v is velocity. Basically sub the numbers in to find the kinetic energy for each. In this case, subbing all the numbers, the smallest change in kinetic energy is the Lineman with a kinetic energy of just 540N.
They have an adaptation called trigger hairs.
