Question

4 Kinetics of the particle:
Binormal, Normal, Tangential Coordinates. - Calculate the angle (Radians) of inclination that the normal force must have (with respect to the binormal axis) that keeps the individual on a circular path at a constant speed of 80 km / h on the roller coaster cart. At the moment of measurement, the Radius = 0.1 km, the weight and mass of the person are deliberately omitted. (Use the relation Tan θ = sin θ / cos θ to obtain the θ)

Answer 1

In binormal direction, there is no force acting. So its component is zero.

In n-direction, we have acceleration with equals to v^2 /

The result does not depend on mass of the moving object.

Force addition in tangential direction has no effect on the solution since the object is moving at constant speed.

N is the normal force and is the angle it makes with the binormal b-axis.
