How could Superman jump a 660 foot building in a single bound?

Firstly, he had to be at least 330 pounds. secondly, we have to remember that the second law of motion states that when there is an action, there is an equal and opposite reaction. when you walk, the friction from the ground pushes back onto your foot. thats what pushes you forword.he had to be 330 pounds, so that his legs could jump and provide enough strengh. the opposite reaction would be the ground giving off 330 pounds of force. therefore, he would shoot into the sky.he also had to have enough speed. he would have to be running very fast. nobody, not even a superhero could jump that high without having a running start. they would have to run pretty fast to jump that high.
