A curve of radius 526 m is banked so that a car of mass 16, Ask an Expert

Academics

A curve of radius 52.6 m is banked so that a car of mass 1.6 Mg traveling with uniform speed 55 km/hr can round the curve without relying on friction to keep it from slipping on the surface.

At what angle is the curve banked? The acceleration due to gravity is 9.8 m/s2.
