If a penny is dropped from a tall building how long does it take for it to hit the ground ?
If dropping the penny from a building that is L1 feet tall takes S1 seconds I guess dropping from a building 2*L1 feet tall won't take 2*S1 seconds. Similarly a coin that is twice as heavy as the penny will take more than S1/2 seconds.
How does the height of the building, weight of the coin and acceleration due to gravity factor in the time taken (assuming there are no other variables like changes in wind speed) ? What is the right mathematical approach to solve this ?
This is not a homework question. I am just curious after seeing this question in a magazine.
