    10. A car is being driven along a straight, level highway at 71.582 mph. The driver taps on the brakes but notices no response. He tries to brake again and realizes the brakes are completely out. There is a field next to the highway with tall grass. The driver veers into the tall grass traveling in a straight line. The car eventually comes to a stop. Later it is measured that the car traveled 184 meters through the grass. How...
