Problem 1: Least Squares Method (Linear / Quadratic)
The distance required to stop an automobile consists of both thinking and braking
components, each of which is a function of time. The following experimental data was
collected to quantify this relationship. Develop bestfit equations for both the thinking
and braking components. Assume a linear fit for the thinking component and a quadratic
fit for the braking component. Use these equations to estimate the total stopping distance
for a car traveling at 110km/h.
