They best represent a wave with zero energy and zero amplitude.
There are no measurements shown in a table that accompanies
this question having any amplitude or energy greater than zero.
Answer:
The distance the piece travel in horizontally axis is
L=3.55m
Explanation:





Now the angular velocity is the blade speed so:
assuming no air friction effects affect blade piece:
time for blade piece to fall to floor

Now is the same time the piece travel horizontally

blade piece travels HORIZONTALLY = (24.5)(0.397) = 9.73 m ANS
Answer:
a = 177.77 [m/s^2]
Explanation:
Este es un problema relacionado con la segunda ley de Newton. La cual nos dice que la sumatoria de fuerzas aplicada sobre un cuerpo debe ser igual al producto de la masa por la aceleración.
De esta manera tenemos:
F = m*a
F = fuerza = 80 [N]
m = masa = 0.45 [kg]
80 = 0.45 * a
a = 80 / 0.45
a = 177.77 [m/s^2]
