Question

Calcula la energia mecánica que tiene un águila de 15kg a 28m de altura si vuela a 17m/s (E=6283,5J)
Ayuda po' favo'

Answer 1

DATOS :
  Calcular :
    La energía mecánica  ( Em ) =? 
    masa ( m)= 15 Kg 
    altura (h) = 28 m
    velocidad ( V ) = 17 m/seg 

    SOLUCIÓN :
         Se resuelve este ejercicio aplicando la formula para calcular
      Energía mecánica que es la suma de la energía cinética mas la 
      energía potencial del águila, cambien se aplica las formulas de
      energía cinética y potencial  de la siguiente manera :

          Em = Ec + Ep 
        Ec = m * V² /2 = 15 kg * ( 17 m/ seg)²/2 = 2167.5 joules 
        Ep = m * g * h = 15 Kg * 9.8 m/seg² * 28 m = 4116 joules .

 Em = 2167.5 joules + 4116 joules = 6283.5 joules . respuesta correcta .
