Si un camión recorre 15 millas por galón de gasolina, con una eficiencia de su motor del 50%¿que distancia, expresada en kilómetros, puede viajar con un consumo de 5 kwh si trabaja al 100% de su capacidad? Considere que el calor de combustión de la gasolina es de 140 mj/galón y 1 milla =1609 m

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
