  1. Use of quadratic function Stopping distance

  2. The stopping distance of a vehicle is proportional to the square of its velocity. This relativeness describes a following formula • where: • h describes the stopping distance in metres • v – velocity of vehicle in km/h • a – constant factor

  3. Exercise • On the icing road, a car driving with velocity of 70 km/h should bring to a stop on the road 74 m. • State the formula of function describing the relativeness of stopping distance to velocity on the icing road. • Estimate the stopping distance with velocity of 50km/h and 100km/h

  4. Data and searched: Solution: Answer: Searched function’s formula: h = 0,015v2

  5. Data and searched: Solution: Answer: Stopping distance on the icy road with V=50km/h equals 37,5m.

  6. Data and searched: Solution: Answer: Stopping distance on the icy road with V=100km/h equals 150m.
