I am having a little trouble with this problem. can someone please HELP!

During a race, a runner runs at a speed of 6m/s. 2 seconds later, she is running at a speed of 10 m/s what is the runner's acceleration?

  • physical science -

    V = Vo + a*t = 10 m/s.
    6 + a*2 = 10
    2a = 4
    a = 2 m/s^2.
