Give me a minute, I'll solve this.
EDIT: Before I do anything. Are you sure that your expression here is correct?:
I_2 B_1 = I_1 B_2
When I expand from:
|F_{12}| = |-F_{21}|
I get:
I_1 l_1 B_1 = I_2 l_2 B_2
Where the lengths of the wires can cancel since they are the...
Yeah, apparently I'm fking retarded. I forgot that Fnet = whatever the Ff is. I thought the object would be carrying some Fapp with it as it still had speed from coming down the inclined plane. I solved the problem.
Thanks for the help. :)
Homework Statement
Block A starts from rest and slides 8m down a frictionless 30 degree angled inclined plane. It then crosses a 4m horizontal surface where the coefficient of kinetic friction is 0.2. What is the velocity of Block A after it has finished crossing the horizontal surface...
