HW Race Car

RACE CAR PROBLEMS
A racecar accelerates from rest down a track at a constant rate of 18m s-2 for 6 seconds.  At the finish line (after 6 seconds), it deploys a parachute in order to slow down more quickly.  It stops over a distance of 200m.

1. What is the velocity of the racecar after 6 seconds?
2. What was the acceleration of the racecar after the parachute deployed?
3. How long did it take the car to stop after the parachute deployed?
4. Make a graph of velocity vs. time for the path of the racecar.
5. Use this graph to find the distance the car traveled during the initial acceleration.
