So the total time for each driver's race is given by: ttot = tr + t ( tr is the reaction time and t is the time accelerating to the finish after the reaction time is over.) The distance (X-X0) is 402.0 meters (start to finish line).
5) USING THE APPROPRIATE EQUATIONS FROM CHAPTER 2 of our online text, fill out the following table that will include the total time for each race car, the final velocity as the race car crosses the finish line (both in units of m/s and mi/hr, (miles per hour). (Note: none of the appropriate Ch. 2 equations will make any use of the reaction time.) Since reaction time is part of the total time, the car with the biggest acceleration and largest final velocity may not win!

SHOW CLEARLY all the math steps, and the equations you used from Chapter 2 with the math steps, to get the values for accelerating time and final velocity values in the table above for each of the cars. SHOW YOUR WORK CLEARLY. ALSO list, according to the table results comparing the total times, which car came in 1st, 2nd, 3rd, and 4th place.
1st place:__________ 2nd:_________________ 3rd________________ 4th____________________
Assume each car has the same negative "braking acceleration" of -13.0 m/s2 during this motion.
The initial velocity for this part of the motion will be the (positive) velocity (v) in m/s you found in the table above, and the final velocity for this part of the motion will be 0 m/s, as the car comes to a complete stop.
For each car above, find the distance the car moves (X - X0) while undergoing this braking acceleration until it comes to a stop, in units of both meters and feet. This will be the distance from the finish line to the final resting place of the car.
Show your work CLEARLY, showing how you use an equation or equations from Chapter 2 to find the distances.
