A Ford Everest skidded into a intersection of Maharlika Highway and Circumferential Road and struck a bystander and continued until it hit one of the electrical post of the highway. Based on the damage to the front of the Everest, the police report estimated that the car was doing 8 kph at the moment of impact on the electrical post. The length of the skid marks was recorded to be 40 m. The road has down hill grade of 5% A test car skidded 14 m. on the same section of the road when the brake is applied from a speed of 40 kph to the halt. Determine the probable speed of the car involved in the accident when the brakes where applied in kph?
