To solve the problem of finding the distance traveled by a car after the driver decides to apply the brakes, we will break it down into steps: ### Step 1: Understand the situation The car is initially moving with a speed \( u \). When the driver sees the red traffic light, there is a reaction time \( t \) during which the car continues to move at speed \( u \) before the brakes are applied. ### Step 2: Calculate the distance traveled during the reaction time During the reaction time \( t \), the car travels a distance given by the formula: \[ ...
