Final answer:
The stopping distance of a car traveling at 50 mph can be calculated using the formula stopping distance = (initial velocity^2) / (2 * acceleration). The stopping distance is approximately 168.225 meters. None of the options provided match this value.
Step-by-step explanation:
The stopping distance of a car depends on several factors, including the initial velocity of the car and the road conditions. In this case, we are given that the car is traveling at 50 mph. To calculate the stopping distance, we need to know the car's deceleration rate. Let's assume a deceleration rate of -6 m/s^2, which is typical for a car braking on dry pavement. Using the formula:
Stopping distance = (initial velocity^2) / (2 * acceleration)
where the initial velocity is 50 mph, which is equivalent to 22.35 m/s, and the acceleration is -6 m/s^2, we can plug in the values to find the stopping distance:
Stopping distance = (22.35^2) / (2 * -6) = 168.225m
Therefore, the stopping distance at 50 mph is approximately 168.225 meters. Since none of the given options match this value, the correct answer is d) None of the above.
