How long in seconds does it take for a car accelerating at 3.5m/s2 to go from rest to 120km/hr

  • Physics -

    First you need to convert the final speed to meters per second. I assume you know how to do that.

    Vfinal = 120 km/h = 33.33 m/s

    The acceleration rate is a = 3.5 m/s^2

    Time required = Vfinal/a = 33.33/3.5
    = 9.5 seconds.
