• Draw a diagram including your chosen coordinate system.

• Label all quantities in the diagram using standard notation.

• List the known and unknown quantities. Circle the unknowns.

• Identify the equation you are using and show all your work. • At the end of each problem, check your answer. Do the units match? Is the answer reasonable? Does the plus or minus sign make sense?

3. In the Daytona 500 auto race, a Ford Thunderbird and a Mercedes Benz are moving side by side down a straightaway at 71.5 m/s. The driver of the Thunderbird realizes that she must make a pit stop, and she smoothly slows to a stop over a distance of 250 m. She spends 5.00 s in the pit and then accelerates out, reaching her previous speed of 71.5 m/s after a distance of 350 m. At this point, how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?
