A motorist suddenly notices a stalled car ahead and slams on brakes with an acceleration of 6.3 m/s^2. Unfortunately, the car collides. Police estimate the first car was moving at 5.0 m/s at the moment of the collison. They also measure skid marks 34 meters long. Assume each car has a mass of 1500kg. The speed limit on the road was 45 miles per hour. Was the incoming car speeding (i.e before applying the brakes)?

4) The brakes on your car can slow you at a rate of 5.2 m/s?. If you are going 137 km/h and suddenly see a state trooper, what is the minimum time in which you can get your car under the 90 km/h speed limit? (The answer reveals the futility of braking to keep your high speed from being detected with a radar or laser gun.)

True or false ? Or neither true and false
