Stuck on this problem

    1. The problem statement, all variables and given/known data
    I figured out the speed of the runner at t=2.0 seconds, but I am stuck on finding v of the runner at the end of the race.

    Q: At the starting gun, a runner accelerates at 1.7 m/s^2 for 4.8 seconds. The runner's acceleration is zero for the rest of the race. what is the speed of the runner at the end of the race?


    2. Relevant equations



    3. The attempt at a solution
