What is the acceleration at the top of a jump

Reference no: EM13315161

Consider a plane that flies due east on a trip, and then returns due west following the same exact route. Imagine also that there are no winds in each trip. Flying due east, the plane flies with the rotation of the Earth, while flying due west, it flies against the rotation. Will the flight times be the same? Different? Why?
The velocity of an object falling in free fall increases with time. Does the acceleration also increase? Why or why not?
Why is that a cat that accidentally falls from a 50-story building hits a safety net below with the same speed as if it fell from a 20-story building?
What is the acceleration at the top of a jump?
