Respuesta:

4.9 × 10³ J

Explicación:

Paso 1: Información provista

  • Masa del coyote (m): 30 kg
  • Velocidad del coyote (v): 65 km/h

Paso 2: Convertir la velocidad del coyote de km/h a m/s

Vamos a usar los siguientes factores de conversion:

  • 1 km = 1000 m
  • 1 h = 3600 s

65 km/h × (1000 m/1 km) × (1 h/3600 s) = 18 m/s

Paso 3: Calcular la energía cinética del coyote (K)

Usarémos la siguiente fórmula.

K = 1/2 × m × v²

K = 1/2 × 30 kg × (18 m/s)² = 4.9 × 10³ J
