Predict the stopping distance at high speed from the low speed and low speed stopping distance.     At high speed, stopping distance is _________ cm.   A 1000 kg car decelerates at a rate of 10 m/s2. What is the magnitude of the force acting on the car?  Where does this force come from?       The friction between your car’s tires and the road is called ____________________.     Water and motor oil have low coefficients of friction.  What does this tell us about stopping distance and road conditions/weather?         What happened if a driver applied the breaks too hard for the road conditions before the invention of anti-lock breaks?         How does the car stop?  What forces are involved?
