SUMMARY
The coefficient of kinetic friction for a sliding car can be calculated using the car's initial speed and stopping distance. In this scenario, a car traveling at 98 km/hr (approximately 27.22 m/s) comes to a stop over a distance of 91 m. By applying the formula for acceleration and the relationship between friction and acceleration, the coefficient of kinetic friction is determined to be approximately 0.75.
