(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a car is exerting 3.000N of force on a hill that rises 3m for each 100m of road. what is the actual weight of the car? how much force do the brakes have to exert to keep the car from rolling down the hill.

2. Relevant equations

a2 + b2 = c2

sin theta= opp/hyp

cos theta=adj/hyp

tan theta=opp/adj

3. The attempt at a solution

i used the a2 + b2 =c2 equation and found that c is 100.04m

I assumed that 3m is the height = a

100m is the length so its = b

and thats how i found c is the side of the hill

i tried cutting the problem into smaller triangles to get the degrees of the hill from the ground to try to get the answr easier, but im not sure...

thank you for all the help.....
