    Answer:

    Given that––:

    The initial velocity of a motorboat, u = 0

    Acceleration of motorboat, a=3.0ms-2

    Time under consideration or time is taken t = 8.0s

    Formula––:

    We know the equation of motion.

    Distance, s = ut + (1/2)at2 —————-(i)

    Substituting the given and known values in the equation (i) we get,

    s= 0 (8) + 1/2 (3) (8)2 

    = 1/2 (3) (64)

    = 3(32)

    = 96

    Therefore, the distance travel by motorboat = 96 m
