Based on the mass and speed data, which object will have the greatest amount of kinetic energy

The object with more mass and steepest ground will have more kinetic energy.

Explanation:

This answer is because gravity pulls harder on objects with more mass. The steeper the ground is and the more mass an object has, the faster it will go. The more an object is moving, the more kinetic energy it has.

I hope this helps, that you have a good rest of your day, and that you get a good score.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
