## Homework Statement

Packages, each one of them with a mass of 1kg, arrives from the moving track to a completely smooth surface of the runway, at a speed of 1 m/s, as described.

Calculate the max angle in which every package begins to veer off the runway track, if the radius of the track (R) is 0.5m

## The Attempt at a Solution

Sigma Fy = -W+N = 0

W = N = 9.81 [N]

N -> 0

Sum of all forces on x = ma

-Wsin(alpha) = m x v

^{2}/R

-9.81sin(alpha) = 9.81 x 1

^{2}/ 0.5

Sin

^{-1}(2) = Math Error
