Final answer:
The distance a car traveling at 70mph will travel before coming to a stop depends on factors such as initial speed, coefficient of friction, and deceleration. Using the formula braking distance = (initial speed)^2 / (2 * deceleration), the approximate braking distance for a car traveling at 70mph would be about 280 feet.
Step-by-step explanation:
When a car is traveling at 70mph and the brakes are applied, the car will travel a certain distance before coming to a stop. This distance is known as the braking distance. The braking distance depends on several factors, including the initial speed of the car, the coefficient of friction between the tires and the road, and the deceleration of the car. To calculate the approximate braking distance, we can use the formula: braking distance = (initial speed)^2 / (2 * deceleration). Assuming a deceleration of 10 ft/s^2, the braking distance for a car traveling at 70mph would be approximately 280 feet.
