    A child slides down a hill on a toboggan with acceleration of 1.8 m/s2. if she starts from rest, how far has she traveled in: 2 seconds

    Answer:

    2.4 m

    Explanation:

    From the question above,

    Applying equation of motion,

    s = ut+at²/2………………….. Equation 1

    Where t = time, u = initial velocity, a = acceleration,  s = distance.

    make s the subject of the equation,

    Given: a = 1.8 m/s²,  t = 2 seconds, u = 0 m/s (from rest)

    Substitute these value into equation 1

    s = 0(2)+1.8(2²)/2

    s = 1.2(4)/2

    s = 2.4 m.

    Hence she has traveled 2.4 m
