Driving Safely Assignment

??????????????????????????

Driving Safely Assignment To drive safely you must be able to stop within the distance between your car and the car in front of you. The distance required varies with the speed at which your car is moving. The force that does negative work on your car to transform all of the kinetic energy into thermal energy is the force of friction within the brakes and between the tires and the road. The thermal energy is then shared among the brakes, tires and the road. For a car with a mass of 1500kg, it would be approximately 12000N. Your challenge is to find the distance needed for stopping at several speeds. Procedure 1. Develop an equation to calculate the stopping distance for any speed by following these steps. a. Start with the information that the work done on the car by the force of friction must be equal to the kinetic energy of the car. Write that relationship in mathematical form. b. Substitute FAd for work and substitute 1/2mv for kinetic energy. c. Solve the equation for Ad 2. Use the table below Speed Stopping Distance Meters per Second (m/s) Kilometers per Hour (km/h) (m) 5 10 15 20 25 30 35 3. Calculate the stopping distance for each of the speeds. Place the answers in the last column 4. Convert the speeds to kilometres per hour and fill in the second column 5. Make a graph of the stopping distance in metres versus speed in kilometres per hour. Put distance (d) on the vertical axis and speed (v) on the horizontal axis. Analysis 1. Describe the shape of the curve on your graph. Is it a straight line or not? 2. What does this graph tell you about stopping at high speeds compared to stopping at lower speeds? 3. What if anything, surprised you the most about your results?
