calculate max volocity of car with road banking and no friction
The normal reaction N.
Resolving in the vertical component,
Ncosθ=mg (which make N >=mg)
Resolving horizontal component,
My question is if we resolve the forces perpendicular to the road:
N = mgcosθ (which would make N < =mg) , it would give a completely different N
. We use N=mgcosθ in inclined plane problems, why can't we use it here?
