    Didn't put do this in class and I'm stuck on this kerboodle question.

    Exact question is 4 The Highway Code states that the braking distance for a car travelling at 30 mph (13 m/s) is 14 m. Calculate the deceleration assumed by the Highway Code.

    0.9 m/s
    141 m/s
    0.5m/s
    6m/s That's the options

    It’s 0.5 as Deceleration = v1-v2 / 2s

    13 - 0
    ——— = 13/28 = 0.46 -> 0.5
