with earth rotating at 1000mph, when we launch ourselves from a trampoline how are we landing back at the same spot compared to launching from a moving car

Question

If we jump high enough to reach a hang time of 1 second, the earth would have moved quarter mile.

Also, why haven’t we devised something that allows us to stay suspended instead of using airplanes with max speed of 500mph

Answer 1

If your car was big enough, you could jump on a trampoline in the car and see the same effect. It is your motion relative to the medium you are in.
