Final answer:
The stopping distance of a car on a dry surface can be calculated using the formula: stopping distance = reaction distance + braking distance. Assuming a reaction time of 0.500 seconds and an initial velocity of 60 mph, it would take approximately 383.2 feet for the car to stop on a dry surface.
Step-by-step explanation:
The stopping distance of a car on a dry surface can be calculated using the formula:
Stopping distance = reaction distance + braking distance
First, we need to calculate the reaction distance, which is the distance the car travels during the driver's reaction time.
Assuming a reaction time of 0.500 seconds:
Reaction distance = velocity × reaction time = 60 mph × 0.500 s = 88.2 ft
Next, we need to calculate the braking distance.
The coefficient of friction for a dry surface is higher than that for a wet surface, resulting in a shorter braking distance.
Given that the car is initially traveling at 60 mph, we can use the braking distance of 90.0 m (295 ft) from the provided information:
Total stopping distance = reaction distance + braking distance = 88.2 ft + 295 ft = 383.2 ft
Therefore, it will take approximately 383.2 feet for the car to stop on a dry surface at a speed of 60 mph.
What is a good braking distance for a car 60-0 miles per hours, how many feet is a good stoppage distance?
