Hamden is driving at 25 m/s. He sees cows are slipping across the road. He applies the break to stop his car when cows are 58 m in front of him. If the coefficient of kinetic friction between the car’s locked tires and the road is 0.52, will the car stop before hitting cows? The mass of the car and Hamden together is 1500 kg.
