The effects of a car travelling up a hill (1 Viewer)

[golfpro]

Ok so the force the car needs to overcome when going up a hill is Wf sin Ө

so if u are given the force needed to be overcome and the speed of the car plus the force at the wheels needed to keep the car at a constant speed, how do u find the slope of the hill in degrees. ?

ermm....i do engineering studies...and...this might b completly wrong but try this:

sin (angle) = force of gravity ACTING ON OBJECT / (mass x gravity)

the force ACTING ON OBJECT is the weight of the car broken up into 2 forces, on of them 90 degrees to surface and one parallel to surface, and one u put in is the one parallel to surface(then times is by gravity)

basicli:

angle = sin-1 x (mass of car acting parallel to surface x gravity) / (mass of car x gravity)

hmm hope that helps.......it might b wrong....sorri if it is
i do physics as well....buh i nva seen a question like that....o well, good luck!
