If a plane is traveling 17,000 mph, going 3,000 miles, from ny to ca, would it be able to land at lax?

Question

17,000mph

Answer 1

Not if it's moving at 17,000 mph!  The typical landing speed for a Boeing 747 is 170 mph.  Anything faster would require a much longer runway.  So your hypothetical aircraft would need to decelerate from 17,000 mph to 170 mph before landing at LAX.
