Explicacion
Dato
m = 70 kg
v = 5 m / s
Ec = ?
Formula
Ec = m V² / 2 = (70 kg)( 5 m / s)² / 2 = 875 Joule
Datos
V = 72 km / hr = 20 m / s
m = 500 kg
Ec = m V² / 2 = (500 kg)(20 m / s)² / 2 = 100000 Joule
m = 1.5 kg
g = 10 m / s²
h = 2 m
Ep = ?
Ep = m g h = (1.5 kg) (10 m / s²)( 2 m) = 29.4 Joule
Respuesta:
La energía cinética es de 560 :)
