  1. Nov 25, 2007 #1
    1. The problem statement, all variables and given/known data

    A 2410 kg car traveling to the west at 22.6 m/s slows down uniformly.

    It takes 6.13355 seconds for the the car to come to a stop if the force on the car is 8880N to the east.

    What is the car's displacement during the time it takes to stop? Answer in m

    2. Relevant equations

    d = vit + .5at^2

    3. The attempt at a solution


    its not 207.8387 or 69.396
