How to Win a Bet with Physics
In a survival show an engineer used a rock and a watch to predict depth of a cavern in order to win a bet. He did win the bet with his estimate being right on target. I believe he used physics to do this. He said the depth of the cavern was 80ft. Is this a feasible way to calculate height? If so could this feat be accomplished with physics?
h= v0t x .5at^2
It seems he did use physics!! They used a rope and measured the cavern at about 82ft this means this is a feasible way to calculate depth.
I replicated this in my dorm down the staircase to check the accuracy of this method for myself, and I found:
h= 10.3m or 32.8 ft
measured value equals 35ft. This method is accurate enough because 2 ft is a jumpable distance when climbing.
