The driver of a 1000 kg car traveling on the interstate at 35 m/s slams on his brakes to avoid hitting a second vehicle in front of him, which had come to rest because of congestion ahead.

Ignore air resistance, at what minimum distance should the brakes be applied to avoid collision with the other vehicle
