1) Jamie is driving at a constant speed of 118 km/h when she suddenly sees a stop sign 60 m ahead. It takes her 0.70 s to react and hit the breaks. Once she begins breaking, she decelerates at a rate of 11m/s². a. Does she come to a stop before the stop sign? b. What would be the maximum speed at which Jamie's car could be at and NOT hit the barrier?
