You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.83 s, and the velocity of the car decreases to + 4.98 m/s. The car’s deceleration has a magnitude of 2.87 m/s2 during this time. What is the car’s displacement?

You are driving toward a traffic signal when it turns yellow. Your speed is the legal speed limit of v0 = 55 km/h; your best deceleration rate has the magnitude a = 5.18 m/s2. Your best reaction time to begin braking is T = 0.75 s. To avoid having the front of your car enter the intersection after the light turns red, should you brake to a stop or continue to move at 55 km/h if the distance to the...

1. Over a time interval of 2.20 years, the velocity of a planet orbiting a distant star reverses direction, changing from +23.7 km/s to -24.2 km/s. Find (a) the total change in the planet's velocity (in m/s) and (b) its average acceleration (in m/s2) during this interval. Include the correct algebraic sign with your answers to convey the directions of the velocity and the acceleration. 2.  A car is traveling at a constant speed of 27.2 m/s on a highway. At...

A motorist is driving at 19.2 m/s when she sees that a traffic light 203 m ahead has just turned red. She knows that this light stays red for 14.5 s, and she wants to reach the light just as it turns green again. It takes her 1.1 s to step on the brakes and begin slowing. What is her speed as she reaches the light at the instant it turns green?

A car is traveling at 13.0 m/s, and the driver sees a traffic light turn red. After 0.590 s (the reaction time), the driver applies the brakes, and the car decelerates at 8.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first sees the red light?

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.7 m/s2 for 3.1 seconds. It then continues at a constant speed for 8.4 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 202 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...
