    -1.5 m/s/s

    Explanation:

    What you know:

    v1 = 3 m/s

    t (Time) = 2 seconds

    v2 = 0 m/s

    So you plug those variables into the equation v2=v1+at and solve for a.

    0 = 3 + 2a

    -1.5=a

    FV - 0 m/s

    IV - 3 m/s

    t - 2 sec

    A = FV-IV/t

    A = 0-3/2

    a = - 1.5 m/s²

    Explanation:

    FV - Final Velocity - > m/s

    IV - Initial Velocity - > m/s

    A - Acceleration - > m/s²

    t - time - > seconds
