Homework Statement
A car (m = 1710 kg) is parked on a road that rises 14.7 ° above the horizontal. What are the magnitudes of (a) the normal force and (b) the static frictional force that the ground exerts on the tires?
Coefficient of static friction: rubber on dry concrete: 1.0
Homework Equations
F=ma
Fs max = coefficient of friction x normal force
The Attempt at a Solution
I drew some pictures, but I'm slightly computer illiterate so..sorry. Anyway, not really sure, but here's what I got:
F= (1710 kg)(9.8 m/s^2)
F= 16758 N
Attempt at solution of the normal force:
16758 N x sin (14.7) = 4252.48 N
Static Frictional Force:
(I'm really not sure of this, but I'll go ahead)
(4252.48 N)(1.0)= 4252.48
I'm just at my wit's end. I've been trying to figure out this problem for two hours straight. I have to enter my answers in online, and I can only have three significant digits, yet I can't enter in scientific notation, so...I just don't know! Help please!
