Trains Collide




Evan is conducting a train going east at 26 meters per second with a mass of 7200 kg. Corey is conducting a train going west at 44 m/s and a mass of 5000 kg.
1 What is the momentum of the trains before they collide?
2. What is the momentum of the trains at the time of the collision?
3. What should happen with Evan's train when it hits Corey's Train?

187200 is what speed evans train is going at. Coreys is going at 220000. So I think Evans train is gonna go flying back to where it came from.

evans momentum is 187200, coreys momentum is 220000. At the time of colision, Their momentum during the collision is the same. Coreys train will push through evans train because it has more momentum

187200 kg m/s east (Evan
220000 kg m/s west (Corey
corys train will go through evans

The momentum of Evan's train is going 187,200 kg m/s east while the momentum Corey's train is going 220,000 kg m/s west. The momentum of the trains during the collision is the same as before the collision. Evan's train should either be derailed, explode, go backward, become engulfed in flames, or a combination of some of them. Or Corey's train will do one of the things in the sentence before this.

187200 Evan
220000 Corey

corys train will win

Anonymous said...

Evan's train (187200) is going slower than Corey's (220000) meaning if they hit each other on a head on collision evans train would go back because it has less velocity.

Gracey said...

Evan- 187200
Corey- 220000

Corey's train is going to go through Evan's.
