A driver is driving at 75 kph when a dog suddenly appeared and stopped at the middle of the road. Determine the distance the vehicle would move before the driver could activate the brakes. Assume PRT is 2.50 secs. If the friction factor is 0.30 and brake efficiency is 45%, determine the braking distance. If the vehicle is 250 m away when the driver sees the dog, will the dog be hit by the vehicle?
