    Answer:

    Acceleration a =-1.75 m/s²

    Explanation:

    Given:

    Initial speed u = 24 m/s

    Final speed v = 10 m/s

    Time taken t = 8 sec

    Find:

    Acceleration a

    Computation:

    a = (v-u)/t

    a = (10-24)/8

    a = -14 / 8

    Acceleration a =-1.75 m/s²

    Answer:

    Accelaration =(v-u)/t

    40-10/20m/s^2

    30/20m/s^2

    1.5m/s^2=accelaeration
