2. A car crashed into an electric pole at a speed of approximately 40 km/hr. According to an investigation of the accident scene, It was found that there were traces of tires scraping the road due to the sudden slowing of the vehicle, a distance of 40 meters on the dry road surface (F = 0.40) and another 55 meters on the grass-covered shoulder before reaching the electric pole (F = 0.20) If the road section has a 3% downhill slope, calculate the average initial speed of the vehicle.
