OK, last time I'll bother you guys today. I'm just having a tough time getting things to work out.(adsbygoogle = window.adsbygoogle || []).push({});

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
