Answer:
21 m
Explanation:
La energía potencial de un cuerpo es la energía que posee el cuerpo en virtud de su posición.
La energía potencial se da como;
E = mgh
Dónde;
m = masa del cuerpo
g = aceleración por gravedad
h = altura del cuerpo
Aquí necesitamos obtener la altura del cuerpo.
h = E / mg
h = 10500/50 * 10
h = 21 m
