Two railroad freight cars with masses 130 Mg and 170 Mg approach with equal speeds of 0.320 m/s . They collide, the lighter car rebounding opposite its original direction at 0.270 m/s .
a) Find the velocity of the heavier car after the collision. Assume the original direction of the lighter car is positive.
b) What fraction of the original kinetic energy was lost in this inelastic collision?
Thanks

Two railroad freight cars with masses 100 Mg and 150 Mg approach with equal speeds of 0.310 m/s. They collide, the lighter car rebounding opposite its original direction at 0.270 m/s . Find the velocity of the heavier car after the collision. Assume the original direction of the lighter car is positive. What fraction of the original kinetic energy was lost in this inelastic collision? Express your answers using two significant figures.
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?...
4. 2/4 points | Previous Answers My Notes Ask Y A railroad freight car weighing 290 kN and traveling at 1.52 m/s overtakes one weighing 214 kN and traveling at 0.920 m/s in the same direction. The cars couple together. (a) Find the speed of the cars after collision. 1.265 m/s (b) Find the loss of kinetic energy during collision. 2259.356Nm (c) If instead, as is very unlikely, the collision is elastic, find the speeds of the lighter car after...
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!
A railroad car of mass 1.85e4 kg moving at 3.14 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.24 m/s. b) How much kinetic energy is lost in the collision? USE THIS DATA: 17400 kg; 3.27 m/s; (help me see how you get the correct answer of 2.39e4 J. 16-4 A railroad car of mass 1.85e4 kg moving at 3.14 m/s collides and...
Two cars collide with each other. The initial speeds are 3 m / s and 2 m / s. Their respective masses are 100kg and 90kg. What will be the car speed of 90kg after the collision.
When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1750 kg car traveling to the right at 1.40 m/s collides with a 1450 kg car going to the left at 1.10 m/s . Measurements show that the heavier car's speed just after the collision was 0.270 m/s in its original direction. You can ignore any road friction during the collision. Part A What was...
QUESTION 9 The two freight cars shown move towards each other in a railroad yard. Car A has a mass MA = 2,853 kg and travels towards the right with a velocity VA = 1.98m/s. Car B has a mass MB = 1,963 kg and travels towards the left with a velocity VB = 1.54 m/s. What is the velocity of the joined freight cars if they couple together when they collide ?

Two balls with masses of 1.50 kg and 6.30 kg travel toward each other at speeds of 13.0 m/s and 4.30 m/s, respectively. If the balls have a head-on inelastic collision and the 1.50-kilogram ball recoils with a speed of 8.60 m/s, how much kinetic energy is lost in the collision?
Two balls with masses of 1.50 kg and 6.10 kg travel toward each other at speeds of 9.0 m/s and 4.00 m/s, respectively. If the balls have a head-on inelastic collision and the 1.50-kilogram ball recoils with a speed of 8.00 m/s, how much kinetic energy is lost in the collision?
