a motor with cnstant speed rate at a highway and exit to acircular ramp of radius 170m. he continue to decelerate at the sameconstnt rate so that 10s after entering the ramp, his speed hasdecreased to 32km/h, a speed which he maintains. Knowing tht atthis constant speed the total acceleration of automobile is equalto one-quarter of its value prior to entering the ramp, determinethe maximun value of the total acceleration of the automobile.

    Assuming Fermat's posted answer is correct:
    32 kph = 80/9 m/s
    ac = v2/r = a0/4
    a0 = 4v2/r = 4(80/9)2/170 =1.859114
    I'n not sure, though, that the solution is this easy,especially since the time of 10 s wasn't used to solve this.
