Question
how much potential energy does a 20 - kg barrel have when it is in the truck whose floor is 5.0 m above the ground? p.e. = j 4900 980 19,600
Step1: Escribir la fórmula de energía potencial gravitacional
La energía potencial gravitacional \( P.E. = mgh \), donde \( m \) es la masa, \( g = 9.8\,\text{m/s}^2 \) es la aceleración debida a la gravedad y \( h \) es la altura.
Step2: Sustituir los valores
Dado \( m = 20\,\text{kg} \), \( h = 5.0\,\text{m} \) y \( g = 9.8\,\text{m/s}^2 \), entonces \( P.E.=(20)(9.8)(5.0) \).
Primero calculamos \( 20\times5.0 = 100 \), luego \( 100\times9.8=980 \).
