I have a buddy that is an engineer. Sometimes when we are in conversation he will pull some assumption out of thin air that he has calculated. I have challenged his claims, but lack the cranial capacity to put up good arguments against his theories. So I am looking for help. Please give me some good arguments against these claims:
A piece of Hardwood firewood costs 50 cents.
It costs 2.5 cents a minute to run hot water. 5 cents for cold. (At his house. He admits variables.)
A 50 yard punt with a hang time of 4 seconds travels at 30 MPH.
The optimal angle to shoot a free throw is 55 degrees.
A gas driven car is only 20% efficient at it's peak. In town only 7%.
