Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be create…

Textbook Question

Chapter 11.3, Problem 11.74P

Car A is traveling on a highway at a constant speed ( v A ) 0 = 60 mi/h and is 380 ft from the entrance of an access ramp when car B enters the acceleration lane at that point at a speed ( v B ) 0 = 15 mi/h. Car B accelerates uniformly and enters the main traffic lane after traveling 200 ft in 5 s. It then continues to accelerate at the same rate until it reaches a speed of 60 mi/h, which it then maintains. Determine the final distance between the two cars.

Students have asked these similar questions

Two cars, A and B, started at the same time and location. Car A started from rest and moved with an acceleration a = 216.18 m/s . Car B also started from rest and moved with velocity v = 151.0914 m/s for 20 seconds after which it maintained its acceleration. It would take 30 seconds for Car A to reach their destination. Find if Car B caught up to Car A before it reached its destination. Assume rectilinear motion for both cars.

A subway car leaves station A; it gains speed at the rate of 4 ft/s² for 6 s and then at the rate of 6 ft/s² until it has reached the speed of 48 ft/s. The car maintains the same speed until it approaches station B; brakes are then applied, giving the car a constant deceleration and bringing it to a stop in 6 s. The total running time from A to B is 40 s. Determine the distance between stations A and B. . Do not type the solution. Show the complete computation/solution with the necessary graphs or diagrams.

Car A is traveling at a constant speed of vA = 130 kph at a location where the speed limit is 100 kph. The police officer in car P observes this speed via radar. As Car A passes P, the car uniformly decelerates to the speed limit for 5 seconds and maintained the motion. Meanwhile, the police car begins to accelerate at the constant rate of 6 m/s2 until a velocity of 160 kph is achieved, and that speed is maintained. Determine the deceleration of car A to reach the speed limit,What is the distance traveled by the police to overtake car A, How long did it take for the police officer to overtake car A?
