A car (m = 1840 kg) is parked on a road that rises 18.7 ° 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?
F=ma Fg=mg Ff=uN
The Attempt at a Solution
errr... what forces cancels out? is it FN=Fg=Ff or is it FN+Fg+Ff=0? i don't remember...
