Q4 / A car 3.5 m in length and traveling at a constant speed of 20 m/s is approaching an intersection, which is 20 m wide. The light turns yellow when the front of the car is 50 m from the beginning of the intersection. If the driver steps on the brake, the car will slow at -4.2 m/s?. If the driver steps on the gas pedal, the car will accelerate at 1.5 m/s². The light will be yellow for 3 seconds. Ignore the reaction time of the driver. To avoid being in the intersection when the light changes to red, should the driver accelerates the car or brake? v,- 20 m/s 3.5 m 50 m 20 m 1 Add file
