    Answer:

    a=1.25m/s²

    Explanation:

    GIVEN DATA

    vi=10m/s

    vf=15m/s

    S=5m

    TO FIND

    a=?

    SOLUTION

    by using third equation of motion

    2as=(vf)²-(vi)²

    2a(5m)=(15m/s)²-(10m/s)²

    10m×a=225m²/s²-100m²/s²

    10m×a=125m²/s²

    a=\frac{125}{10}

    a=12.5m/s²
