A car slams on its brakes, coming to a complete stop in 4 sec. The car was traveling north at 60 mph. Calculate the acceleration

  • Physics -

    60 mph = 88 ft/s

    acceleration = (change in V)/(time) =
    (88 ft/s)/4s = 22 ft/s^2

    That is about (2/3) g

    The acceleration DIRECTION is south, in case they want to know that too
