- 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 5.80m. 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 was moving at 1.20 m/s?Sammy with a mass of 20 kg and his mother the mass of 40 kg are at rest 10 m apart. The father of mass 80 kg slides along the path at 15 m/s. He collides with the mother and she bounces ahead to collide with Sammy. If all collisions are perfectly elastic and one dimensional and there is no friction on the straight and level path, calculate the speed of SammyA truck with a mass of 1600 kg and moving with a speed of 13.5 m/s rear-ends a 585 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. V car 6.27 m/s V truck = 19.77 X m/s
- A bullet of mass mb is fired horizontally with speed vi at a wooden block of mass mw resting on a frictionless table. The bullet hits the block and becomes completely embedded within it. After the bullet has come to rest relative to the block, the block, with the bullet in it, is traveling at speed uf.

If the combined blob doesn't move just after the collision, what can you conclude about the relative speeds of the balls before they collided?Speed of 10 kg ball = _ ✕ speed of 1 kg ball.An Amazon package of mass 2 kg is released from rest at an Amazon warehouse loading dock and slides down a 3.0-m-high, frictionless chute to a waiting truck. Amazon warehouse workers have no breaks, but the truck driver really needed to use the restroom, so he sneaked out without having removed the previous package, of mass m, from the bottom of the chute. Suppose the packages stick together. If their common speed after the collision is 3 meters per second, what is the mass of the package at the bottom of the chute?
- A ball has a mass of 10-Kg and is traveling to the right at 30 m/s. A second ball, which is suspended from a string and has a mass of 15-Kg, is traveling to the left at 12 m/s.
