You are driving a car behind another car. Both cars are moving at speed 80 km/h. Assume your brakes are just a bit harder than the car ahead and your reaction time is 0.60 s.
To calculate the stopping distance, we need to consider three factors: the reaction distance, the braking distance, and the total stopping distance.
First, let's calculate the reaction distance. The reaction distance is the distance traveled by the car during the driver's reaction time. Assuming your reaction time is 0.60 seconds and the cars are moving at a speed of 80 km/h (which is equivalent to 22.22 m/s), we can calculate the reaction distance using the formula:
Reaction distance = Speed x Reaction time
Reaction distance = 22.22 m/s x 0.60 s
Reaction distance = 13.33 meters
Next, let's calculate the braking distance. The braking distance is the distance covered by the car while the brakes are being applied, leading to a complete stop. However, we need additional information or assumptions to calculate the braking distance accurately, such as the deceleration of the car and the coefficient of friction between the tires and the road surface.
Finally, let's calculate the total stopping distance by adding the reaction distance and the braking distance. Since we don't have information about the braking distance, we can't provide an exact answer.
Total stopping distance = Reaction distance + Braking distance
Total stopping distance = 13.33 m + Braking distance
To obtain the complete answer, we need to know the specific braking distance, which depends on various factors like the vehicle's braking system, road conditions, tire grip, and driver's skill.
