Question
three mountain climbers set out to climb a mountain from the same altitude and all arrive at the same location at the top. mountain climber a took a long gradual slope to the top, b went a steeper but shorter path, and c tackled the sheer straight side to the top. assume all three climbers weigh the same. which did the most work?
o c
o all did the same amount of work
o a
o b
Step1: Formula de trabajo
El trabajo \(W\) en un movimiento contra la gravedad se calcula como \(W = mgh\), donde \(m\) es la masa, \(g\) es la aceleración gravitacional y \(h\) es la altura vertical.
Step2: Análisis de los montañistas
Como los tres montañistas tienen la misma masa (\(m\)), la misma aceleración gravitacional (\(g\)) actúa sobre ellos y suben a la misma altura (\(h\)) (ya que parten de la misma altitud y llegan al mismo lugar en la cima). Entonces, \(W_A=mgh\), \(W_B = mgh\) y \(W_C=mgh\).
