Final answer:
The distance it takes for a fully-loaded tractor trailer to come to a complete stop depends on multiple factors, such as the initial velocity of the truck, the mass of the truck, and the coefficient of friction between the tires and the road.
Step-by-step explanation:
The distance it takes for a fully-loaded tractor trailer to come to a complete stop depends on multiple factors, such as the initial velocity of the truck, the mass of the truck, and the coefficient of friction between the tires and the road. To calculate the total stopping distance, we need to consider both the distance covered during the driver's reaction time and the distance covered while braking. A formula commonly used to calculate the stopping distance is: Stopping distance = Initial velocity * Reaction time + (1/2) * (Initial velocity)^2 / Deceleration.
For example, let's say the initial velocity of the fully-loaded tractor trailer is 20 m/s, the driver's reaction time is 0.5 seconds, and the deceleration is 4 m/s^2. Plugging these values into the formula, we get: Stopping distance = 20 * 0.5 + (1/2) * 20^2 / 4 = 10 + 100 / 4 = 10 + 25 = 35 meters.
Keep in mind that the stopping distance can vary depending on road conditions, driver reaction time, and other factors, so it is important for drivers to maintain a safe distance from other vehicles on the road.
