he kicked it 10 feet straight up into the air? i think this works.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
