Two cars start moving from repose at the same place. The first one does this with a constant acceleration for 2.7m/s2. Two seconds after, the second car starts; if it manages to catch up with the first car 178m ahead, then what was its acceleration?

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 5.6 m/s2 for 3 seconds. It then continues at a constant speed for 7.8 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 178.16 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

8). (15 points) Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.50 m/s2. This car moves toward a second car that is 32.0 m away. The second car is moving away from the first car and is traveling at a constant speed of 4.50 m/s. a) Where will the cars collide? b) How long will it take for the cars to collide?

In a quarter-mile drag race, two cars start simultaneously from rest, and each accelerates at a constant rate until it either reaches its maximum speed or crosses the finish line. Car A has an acceleration of 11.6 m/s2 and a maximum speed of 108 m/s. Car B has an acceleration of 11.7 m/s2 and a maximum speed of 91.0 m/s. Which car wins the race, and by how many seconds?

Two runners in a 100 m race start from the same place. Runner A starts as soon as the starting gun is fired and runs at a constant speed of 8.00 m/s. Runner B isn’t really paying attention and starts running 2.0 s later and runs at a constant speed of 9.3 m/s. a. Draw a position vs time graph for each runner. b. Who wins the race? c.

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 3.9 m/s2 for 4.7 seconds. It then continues at a constant speed for 10.2 seconds, before applying the brakes such that the car's speed decreases uniformly coming to rest 254.16 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

Car A and B start a race from rest. Car A starts with an acceleration of 100 m/s^2 and after 10s increases with acceleration to 200 m/s^2. Car B starts with an acceleration of 50 m/s^2 and after 5s increases the acceleration to 300 m/s^2. 1) What is the distance between cars after 1s 2) What is the velocity of each car after 1s 3) After 30 seconds which car is ahead?
