Kinetic Energy = (1/2) (mass) (speed)
First runner: KE = (1/2) (45kg) (49 m/s) = 1,102.5 Joules
Second runner: KE = (1/2) (93kg) (9 m/s) = 418.5 Joules
The <em>first runner </em><em>has 163</em>% more kinetic energy than the second runner has.
My guess is A. I'm not 100% positive but i'm pretty sure.

If atoms lose , they become more organized.
When energy is removed from a given amount of atoms, they enter a more organized state because their attractive forces overcome their repulsive forces, which causes them to come closer. This is observed when a gas is condensed to a liquid, and then also when a liquid freezes into a solid. This moving closer also limits the motion of the particles.
