Respuesta:

60°

Explicación:

Paso 1: Información dada

  • Distancia recorrida (d): 2000 cm
  • Fuerza aplicada (F): 80 N
  • Trabajo realizado (W): 800 J

Paso 2: Convertir "d" a metros

Usaremos el factor de conversión 1 m = 100 cm.

2000 cm × 1 m/100 cm = 20 m

Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)

W = F × d × cosθ

800 J = 80 N × 20 m × cosθ

θ = 60°
