Two Train cars are on a smooth level track. Car 1 has an initial mass of 10,000 kg and an initial speed of 18 m/s. car 2 is at rest and has a mass of 17,000 kg. As car 1 rolls it passes under a loading chute and 3,000 kg of corn are deposited in car 1. Car 1 then collides and connects to car 2.
A. what is the initial momentum of car 1?
B. what is the speed and kinetic energy of car 1 after the corn is loaded?
C. what is the speed and kinetic energy of the connected cars after the collision?
