    Answer:

    1.09 m/s²

    Explanation:

    Given:

    Final speed of the sprinter (v) = 10.4 m/s

    Initial speed of the sprinter (u) = 0 m/s (As the sprinter starts from rest position)

    Time taken to reach the speed(Δt) = 9.58 s

    Average acceleration is defined as the rate of change of velocity.

    So, the acceleration of the sprinter is given as:

    a=\frac{v-u}{\Delta t}

    Plug in all the given values and solve for acceleration, ‘a’. This gives,

    a=\frac{10.4-0}{9.58}\\\\a=1.09\ m/s^2

    Therefore, the magnitude of the average acceleration of the sprinter is 1.09 m/s².
