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 v2/R
-9.81sin(alpha) = 9.81 x 12/ 0.5
Sin-1(2) = Math Error
?
