Answer #1

From the conservation of momentum

Mava+mbvb= (ma+mb) v

V= 2853*1.98-1963*1.54/(2853+1963)

V= 5648.94-3023.02/4816= 0.545 m/s

In the railroad freight yard, an empty freight car of mass m rolls along a straight level track at 1.20 m/s and collides with an initially stationary, fully loaded boxcar of mass 5.20m. The two cars couple together on collision. A). What is the speed of the two cars after the collision? B). Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one...

physics-- two cars with the mass of 300 kg (each) move towards eachother, collide head on and get joined together. before the collision: car 1 is traveling at 41 m/s and car 2 is traveling at 65 m/s. what is their speed immediately after the collision?

Your uncle works at the railroad freight yard, and he has asked you to watch the yard hands couple 30,000-kg boxcars together. As he leaves to get a sandwich, he tells you, "Whatever you do, don't let those cars bang together too hard. The coupling between the cars will take only 8,000 J on a hit before it shatters." You ask how hard is too hard, but your uncle has already ducked out. How fast can one moving car bump...

An 18000 kg freight car rests against a spring bumper at the end of a railroad track. The spring has constant k=3.2×10^5 N/m. The car is hit by a second car of 9400 kg mass moving at 8.0 m/s , and the two couple together. Find the maximum compression of the spring. Find the speed of the two cars when they rebound together from the spring.

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...

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!
