    A car starts from rest at a stop sign. It accelerates at 5.02 m/s2 for 7.24 seconds, coasts for 2.22 s, and then slows down at a rate of 4.51 m/s2 for the next stop sign. How far apart are the stop signs?


    2. Relevant equations

    Im not sure how to start this problem

    3. The attempt at a solution
