Two cars are driving on the freeway. Car A is moving at 33.5 m/s when it realizes it’s closing in on the car in front of it (car B). Car B in front of car A is 61.0 m away and moving at 29.1 m/s when car A hits the brakes, decelerating at 1.22 m/s2. Car B also notices this, and 1 second later accelerates at 0.914m/s2. (a) Is there an accident? (b) If not, what is the distance of their closest approach?

You're speeding at 82 km/h when you notice that you're only 13 m behind the car in front of you, which is moving at the legal speed limit of 60 km/h. You slam on your brakes, and your car negatively accelerates at 4.4 m/s2 . What will be the distance between the cars at their closest approach?

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...

You are driving on a highway at 30.0 m/s when a car enters the highway 30.0 m in front of you traveling at 10.0 m/s and accelerating at 2.00 m/s2. (a) If you do not break (or change lanes), will you hit the car? If so, how far will you travel before hitting the car? (b) What acceleration is necessary so that you don’t get any closer than 6.00 m from the car?

Speedy Sue, driving at 34.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 170 m ahead traveling with velocity 5.10 m/s. Sue applies her brakes but can accelerate only at ?2.00 m/s2 because the road is wet. Will there be a collision? Question 1: Yes or No If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sue's car and the van, and...

a) While entering a freeway, a car accelerates from a speed of 20.0 m/s at a rate of 2.51 m/s2 for 6.00 s. How far does the car travel in those 6.00 s? (To solve this part, first identify the unknown, and then discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, check your units, and discuss whether the answer is reasonable.) b) What is the...
