The velocity of the rolling cheese can be estimated using conservation of energy. The change in elevation from the cheese shack at **718 meters** to the bottom of the hill at **653 meters** is 65 meters. All of the potential energy converts to kinetic energy of motion. The relationship is:

(3/4) * mass * **velocity**^2 = mass * gravitational acceleration * change of elevation

Solving for velocity:

**velocity** = sqrt(1.3333 * gravitational acceleration * change of elevation)

Using 9.8 meters/sec^2 for the gravity we get a speed of 29 meters/sec or 65 mph!

9.8 meters per second squared is an

**acceleration due to **gravity, not gravity. Gravity (gravitational force) is measured in Newtons.

but it is really just semantics

Opps, I missed the gravitational acceleration, sorry I butted in.

When I first saw the rolling cheese, two things came to my mind. Delta PE = Delta KE and Delta p = F delta t and a very horrible philmination if it hit anyone....lol
