Two railroad freight cars with masses 130Mg and 140Mg approach withequal speeds of 0.330m/s . They collide, the lighter car reboundingopposite its original direction at 0.310m/s .
Find the velocity of the heavier car after the collision. Assumethe original direction of the lighter car is positive.
What fraction of the original kinetic energy was lost in thisinelastic 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 1850 kg car traveling to the right at 1.40 m/s collides with a 1350 kg car going to the left at 1.10 m/s. Measurements show that the heavier car's speed just after the collision was 0.250 m/s in its original direction. You can ignore any road friction during the collision.

A.) What is the speed of the lighter car just after collision?

B.)Calculate the change in the combined kinetic energy of the two-car system during this collision.

A railroad car of mass 2.00 x 104 kg moving at 3.00 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 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? (b) How much kinetic energy is lost in the collision?

A freight car with a mass of 25000kg rolls down an inclined frictionless track through a vertical distance of 1.5m. At the bottom of the incline, on a level track, the car collides and couples with another 20000kg freight car that was at rest. Calculate a.) gravitational potential energy of first car at the top of the track, b.) velocity of the first car on the level track before collision, c.) total kenetic energy of the two cars before collision, d.) total momentum of the two cars before collision, e.) velocity of coupled cars after velocity, f.) kinetic energy of the coupled cars after the collision. What percentage of the initial kinetic energy is lost in the collision?
