a car on a straight level road is stopped for a red light.on a green light it uniformly accelerates to a velocity of 18m/s in 3 minutes.what is its acceleration?

  • physlcs - ,

    Acceleration has a unit of
    m/s².

    from 0 to 18m/s in 3 minutes</>
    is the same as
    0 to 18 m/s in 180 seconds, which translates to
    18m/s / 180 seconds
    or
    0.1 m/s²

    A bicycle does better than that, haha!
