OK, last time I'll bother you guys today. I'm just having a tough time getting things to work out.
A curve of radius 30m is banked so that a car can round the curve at 48km/h even if the road is frictionless. Calculate the banking angle theta for these conditions.
I have;
tan(theta) = v^2 / gr
tan(theta) = 48^2 / (9.8 * 30)
tan(theta) = 7.8367
theta = 82.7 deg
The book has 31 deg.
Any ideas?
Thanks,
Bernie
