Three train carriages, A, B and C, are on the same track with B between A and C. They all have the same mass, ?, and B is coupled with C. The coupling can be described as a massless spring with the spring constant ?. B and C stand still on the track, while A moves towards B at a constant speed ?0.
A abuts B and undergoes a completely elastic collision. What is the velocity of A (??), B (??), and C (??) at the moment immediately after the collision?

While stuck at a railroad crossing, you notice a full train car (m1 = 9000kg) is moving to your left with a speed of 9m/s. Two seperated empty train cars (m2 & m3 = 3000kg each) are on the same track moving to the right, each with a speed of 3m/s. There are two succesive collisions. First m1 and m2 hit and stick together. That pair (m1 & m2) then runs into m3. In this second collision, the air bag...

Two carts are rolling to the right along the same level track. Cart 1 (m1 = 3.81 kg) is in the rear, rolling at a speed of 6.25 m/s and catching up to cart 2, rolling at 3.07 m/s. Round final results to 3 digits. a) Cart 1 of course overtakes and collides with cart 2. Velcro pads on the carts make them stick together during the collision, after which they both continue rolling right, but at a speed of...

The distance between stations A and B is 250 miles. Train A leaves station A toward B with constant speed 60 miles/hr while at same time train B leaves station B toward A with initial speed 0 but with constant acceleration 20 miles/hr^2. When these two trains will meet? How far from station A when these two trains meet? Please Solve using a Mat Lab Line of Code. Please explain.

Two air carts of mass m1 = 0.83 kg and m2 = 0.45 kg are placed on a frictionless track. Cart 1 is at rest initially, and has a spring bumper with a force constant of 690 N/m. Cart 2 has a flat metal surface for a bumper, and moves toward the bumper of the stationary cart with an initial speed v= 0.66 m/s . Assume that positive x-axis is directed toward the direction of motion of cart 2. a)What...

In a lab experiment, two identical gliders on an air track are held together by a piece of string, compressing a spring between the gliders. While they are moving to the right at a common speed of 0.500 m/s, one student holds a match under the string and burns it, letting the spring force the gliders apart. One glider is then observed to be moving to the right at 1.300 m/s. (the string and spring both have negligible mass). a)...

The drawing shows two identical systems of objects; each consists of the same three small balls connected by massless rods. In both systems the axis is perpendicular to the page, but it is located at a different place, as shown. The same force of magnitude F is applied to the same ball in each system (see the drawing). The masses of the balls are m1 = 8.2 kg, m2 = 5.3 kg, and m3 = 7.7 kg. The magnitude of...
