Question

a rock with mass of 5.0 kg is carried up a small hill 10 meters high. what is the potential energy of the rock at the hilltop? p.e. = 245 490 4900

Explanation:

Step1: Escribir la fórmula de energía potencial gravitacional

La energía potencial gravitacional \( P.E. = mgh \), donde \( m \) es la masa, \( g \) es la aceleración gravitacional (\( g = 9.8\ m/s^{2} \)) y \( h \) es la altura.

Step2: Sustituir los valores dados en la fórmula

Dado que \( m = 5.0\ kg \), \( h = 10\ m \) y \( g = 9.8\ m/s^{2} \), entonces \( P.E.=(5.0)(9.8)(10) \).
Calculando \( (5.0)(9.8)(10)=5\times98 = 490\ J \).

Answer:

490
