If 2 lines are graphed on a distance vs. time graph showing constant speeds, then how would you tell which runner was faster?

The steeper line would be the faster runner.

What is mechanical energy and what is the equation for calculating total mechanical energy?
Mechanical energy is the energy that an object has because of its motion or position/condition. (combined potential and kinetic energy) Mechanical energy = KE + PE
