Aircraft climb when they start flying and decend when they land. This is usually at a very small rate ( to avoid upsetting the passengers). If you are talking about an aircraft landing then 500 feet per minute is about right
1 foot.
Well the average terminal velocity ofr an average sized jumper is 120mph. I fall at 120mph and fall 10,000 feet in 45/50 seconds so I guess about 213 feet per second.
The penny drop a height after 1 second penny is on the ground
40000 feet = 7.6 miles
About 41 feet per second.

In the tenth second, an object in free fall will have fallen approximately 490 meters. This is because the distance fallen increases by 1/2 the acceleration of gravity each second squared (9.8 m/s^2).

146.6 feet per second.
About 41 feet per second.
About 4.55 feet per second.
If a car is moving at 100 feet per second, then it is traveling at 100 feet per second.
About 4.2 miles.
73.33 feet per second.
100 mph = 146.66 feet per second
