I think I understand, but where do you find force?

I used F=ma so: F=(10,000kg)(1)= 10,000
Laura0901
Which I think is definitely wrong! I don't see how to use acceleration in the equation F=Mmg..

Why is that wrong? (Except of course you left the units off.) 10,000 NLaura0901 said:I used F=ma so: F=(10,000kg)(1)= 10,000
Now use you "friction" equation: Ff = μN = μmg.

10,000 N is the force?
Laura0901
I used that friction formula to get:
10000=M(10000)(9.8)
10000=M(10000)(9.8)

That's the force required to stop a 10,000kg train in 30 seconds if it was traveling at 30 m/sec. Friction is the force that's employed to stop the train.Laura0901 said:10,000 N is the force?

which equaled to .1020408163
Laura0901
Which doesn't have units because it's a coefficient
