MATH UNIT ONE PROJECT: FULL STOP AHEAD

Linzi Long



ACTIVITY ONE: Table and Graph

The distance between one vehicle and another is something to be aware of on the road. This activity allows you to calculate adequate stopping distance when traveling at different speeds.

ACTIVITY TWO: Calculating

Why do you think the estimates of speed do not double when the skid mark doubles in length? Based on these results, what conclusions can you make about safe distances between cars?    The skid mark length is not directly proportional to the speed the car is traveling, what creates the skid mark is friction. Speed does not affect the amount of friction,  the stopping distance is the only factor that affects the skid mark.


ACTIVITY THREE: Reasoning

A safe distance to travel behind a car going about 47 mph, is 150 feet.

ACTIVITY FOUR: Communicating
