A force acting on tran A causes it to have an acceleration of magnitude 4.0x10^-1 m/s2. Train A has six cars wita total mass of 3.0x10^5kg, and a locomotive of mass 5.0x10^4kg. Train B has a locomotive of the same mass as train A, and four cars with a total mass of 2.0x10^5kg. If the same force acts on train B, what will be its acceleration? Ignore friction.

Question

A force acting on tran A causes it to have an acceleration of magnitude 4.0x10^-1 m/s2. Train A has six cars wita total mass of 3.0x10^5kg, and a locomotive of mass 5.0x10^4kg.  Train B has a locomotive of the same mass as train A, and four cars with a total mass of 2.0x10^5kg.  If the same force acts on train B, what will be its acceleration?  Ignore friction.

experimentx · Answer

calculate force on A,
use that force on B.

anonymous · Answer

The net force ?

experimentx · Answer

wita total mass of 3.0x10^5kg <--- I am not sure about this, if this is total mass,then use it on Newtons second law, to find the force.

anonymous · Answer

okay, i will do that and then get back to you

shayaan_mustafa · Answer

experimentX is right and you have to add locomotive mass dude.

anonymous · Answer

figured it out and got the right answer, i found the net force and used that to find the accelertation of Train B.  thank you @experimentX !

experimentx · Answer

good job ... if you are student, understanding question is the most important thing.
Ironically, I'm still not quite clear about your question, though I know how to solve it.

anonymous · Answer

its a textbook question that i have to complete for class as i am still a student.

shayaan_mustafa · Answer

force on train A will be some thousand of newton's. isn't you gotten?
