    Answer:

    5 m/s²

    Explanation:

    From the questio,

    Acceleration (a) = Change in velocity(Δv)/time(t)

    a = Δv/t

    a = (v-u)/t……………… Equation 1

    Where v = final velocity, u =  initial velocity, t = time

    Given: v = 15 m/s, u = 5 m/s, t = 2 seconds

    substitute these value into equation 1

    a = (15-5)/2

    a = 10/2

    a = 5 m/s².

    Hence her accleration is 5 m/s²
