Question
always use significant figure rules. remember that these rules apply to all numbers that are measurements. calculate the force at sea level that a boy of mass 50 kg exerts on a chair in which he is sitting. n 50 490
Step1: Aplicar la fórmula de fuerza
La fuerza \( F \) que ejerce un objeto sobre una superficie es \( F = mg \), donde \( m \) es la masa y \( g \) es la aceleración debida a la gravedad (\( g = 9.8\,\text{m/s}^2 \) en el nivel del mar).
Step2: Sustituir valores
Dado \( m = 50\,\text{kg} \) y \( g = 9.8\,\text{m/s}^2 \), entonces \( F=(50\,\text{kg})(9.8\,\text{m/s}^2) \).
Step3: Calcular
\( F = 490\,\text{N} \).
