Subject:  Curve of Best Fit for Car's Skidding Distance

the breaks are applied as (MPH, feet):
(20, 19)
(30, 43)
(40, 76)
(50, 119)
(60, 171)
(70, 233)
Since this is obviously an observation of physics, I wonder what function of
speed TxDOT used to find these distances. Using the tool at
http://www.shodor.org/interactivate/activities/flydata/index.html I've decided
that the closest I can get to these data is "f(x)=x^1.3139". But I know this
can't be the real function, because it should have a Yintercept of 0, not
39 (as it takes any object traveling at 0 MPH exactly 0 seconds to
"stop").
Does anyone have an idea how to solve this? Thanks!
