Circular Motion Problem
A train is moving around a circular track of radius 800m at an uniform speed of 80km/hr. A light inelastic wire is attached to the roof of the carriage and has a small package attached at the other end.
Qns: Find the angle of inclination of the wire with the vertical. (Hint: the radius of the circle described by the package is approx. the same as that of the circular track.)
The answer at the back of the book says 3.60 degrees, but I'm having trouble to approach this question after resolving the forces on the package...
Anyone helps will be greatly appreciated,
and thanks in advance.
