Question

calcular la EC de un balon de 72kg,si se patea y se mueve a 1.2m/s​

Answer 1

Respuesta:

51.8 J

Explicación:

$Ec = \frac{1}{2} mv {}^{2} \\ Ec = \frac{1}{2} (72kg)(1.2 \frac{m}{s} ) {}^{2} \\ Ec = \frac{1}{2} (72kg)(1.44 \frac{m {}^{2} }{s {}^{2} } ) \\ Ec = \frac{103.60kg \: m {}^{2} }{2s {}^{2} } \\ Ec =51.8J$
