As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface. The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m1 = 14.5 kg and m2 = 42.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1...

Two railway cars are on a straight railroad track. The first, with mass 8000 kg, moves slowly at a velocity of 0.05 m/s to the right in the direction of the second car of mass 15000 kg, which is stationary. (a) What is the total momentum (relative to the ground) of both cars together? kg m/s They collide and stick to each other. What is the total momentum right after the collision? For the short times involved, you can take...
As shown in the figure below, object m1 = 1.60 kg starts at an initial height hij = 0.305 m and speed V1 = 4.00 m/s, swings downward and strikes in an elastic collision) object m2 = 4.55 kg which is initially at rest. 4.00 m/s m2 (a) Determine the speed of m(in m/s) just before the collision. X After you are convinced that energy is conserved as m, swings downward for the collision with me, see if you can...
A railroad car moving at a speed of 3.41 m/s overtakes, collides, and couples with two coupled railroad cars moving in the same direction at 1.40 m/s. All cars have a mass of mass 1.07 x 105 kg. Determine the following. (a) speed of the three coupled cars after the collision (Give your answer to at least two decimal places.) m/s (b) kinetic energy lost in the collision Additional Materials E eBook
The bumper cars at an amusement park collide as one approaches the other directly from the rear. Car A has a mass of 401 kg and a velocity of 5.0 m/s. Car B has a mass of 481 kg and a velocity of 3.3 m/s. The coefficient of restitution is 0.63. A. Determine the velocity of car A immediately after the collision. B. Determine the velocity of car B immediately after the collision. C. Determine the change in momentum of...
In assembling a train from several railroad cars, two of the cars, with masses 2.0 X 10^4 kg and 4.0 X 10^4 Kg are rolled toward each other. When they meet, they couple and stick together. The lighter car has an initial speed of 1.5m/s. The collision causes it to reverse direction at .25m/s. A) Write down the statement of conservation of momentum in the case of perfectly inelastic collision/ B) What is the initial momentum of the lighter car?...

A railroad freight car weighing 28000 kg and traveling at 6.0 m/s overtakes one weighing 19000 kg and traveling at 4.0 m/s in the same direction. If the cars couple together, find (a) the speed of the cars after collision and (b) the loss of kinetic energy during collision. (c) Is this collision elastic or inelastic? Please explain the steps. Thank you!
