Question

Does this even make sense?

Answer 1

Yes it does! You're required to find the magnitude static friction (the force that just keeps it from rolling down the incline).

Answer 2

How am i suppose to do that? I don't remember being taught that :P

Answer 3

\[F _{s}=F _{Nx}\]

Answer 4

Static Friction is thesame as horizontal component of car's weight \[\to F _{N} \sin 10=2000 \times 0.1736=347 lbs\]

Answer 5

Clearly, we don't need the vertical component here...

Answer 6

Do you understand?

Answer 7

i have never met these formulas

Answer 8

I see. So, you just wanted to know if it made sense, right?

Answer 9

I guess you do now (:

Answer 10

yes, kind of weird how they asked a question that i couldn't know how to do :/ but thank you!

Answer 11

Ah, ok. Yw. np, may be you should try out a decent text on newton's laws of motion. It would help you see the bigger picture. (:
