You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.45 s, and the velocity of the car decreases to + 4.71 m/s. The car’s deceleration has a magnitude of 3.54 m/s2 during this time. What is the car’s displacement?

You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.75 s, and the velocity of the car decreases to + 5.03 m/s. The car’s deceleration has a magnitude of 3.11 m/s2 during this time. What is the car’s displacement
You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.18 s, and the velocity of the car decreases to + 4.73 m/s. The car’s deceleration has a magnitude of 3.40 m/s2 during this time. What is the car’s displacement?
Refer to Multiple-Concept Example 5 to review a method by which this problem can be solved. You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.24 s, and the velocity of the car decreases to4.87 m/s. The car's deceleration has a magnitude of 3.08 m/s2 during this time. What is the car's displacement? the tolerance is +/-590
A motorist is traveling at 54
km/h when she observes that a traffic light 240 m ahead of her
turns red. The traffic light is timed to stay red for 24 s. If the
motorist wishes to pass the light without stopping just as it turns
green again, determine (a) the required uniform deceleration of the
car, (b) the speed of the car as it passes the light.
A car is moving at 20.0 m/s when the driver sees a traffic light ahead turn red. The driver applies the brakes slowing uniformly to a stop. As the car slows to a stop, it travels a distance of 60.0m. A) Please draw an acceleration vs time graph. B) Please draw a velocity vs time graph. C) Please draw a position vs time graph.
You are driving towards a traffic signal when it turns yellow. You are travelling at 15.5 m/s and as you break, you decelerate at a constant rate of 3.5 m/s2. Your reaction time before breaking is 0.75 s. If the distance to the intersection is 40 m, willl your car stop before the intersection? If the duration of the yellow light was 3.2 seconds, would you have been able to pass the traffic signal before the light turned red?
You are driving to the grocery store at 20 m/s . You are 1.10×102m from an intersection when the traffic light turns red. Assume that your reaction time is 0.79 s and that your car brakes with constant acceleration. A) How far are you from the intersection when you begin to apply the brakes? B) What acceleration will bring you to rest right at the intersection? C) How long does it take you to stop after the light turns red?
You are driving to the grocery store at 16 m/s. You are 160 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.50 s and that your car brakes with constant acceleration. Part A What magnitude braking acceleration will bring you to a stop exactly at the intersection? E
A person driving her car at 49.0 km/hr approaches an intersection just as the traffic light turns yellow. She knows that the yellow light lasts only 1.80 s before turning to red, and she is a distance D = 35.0 m away from the near side of the intersection. If she decides to stop, how far from the intersection will she come to a stop? The intersection is W =11.0 m wide. Her car's maximum deceleration is -5.70 m/s2. Ignore...
