How manyuniversities benefitted when an emeritus professor won a distinguished award (which has included NobelPrizes in the past)? The fact of the matter is, given the cost-benefits of granting emeritus status, anyuniversity in question has always been far-and-away the winner.
where g is the acceleration of gravity. The value for g on Earth is 9.8 m/s/s. The above equation can be used to calculate the velocity of the object after any given amount of time when dropped from rest. Example calculations for the velocity of a free-falling object after six and eight seconds are shown below.
Almost all airplanes hit the runway vertically less than a 100 feet per minute, which is like less than traveling 2 feet per second. However, the horizontal speed varies greatly. Glides can land at speeds below 40 mph, while large comerical airliners will land at around 150-170 mph. It depends on the design of the wing, the wing loading, and most importantly, when it will stall. Almost all aircraft basically stall (sometimes fully, sometines partically) upon landing.
