OK so how do you do it without data acquisition equipment at Bonneville?
Everybody can't afford it. Delta V is velocity and Delta T is what....time?
Surely not Temperature.....Then what? It doesn't seem to be intuitively
obvious....at least to me.
Maybe hold the speed constant (as constant as possible) through mile 4 and
then coast through mile 5 and get the exit speed????? What is the formula?
Anybody know?
