Alright, well I haven't taken physics yet, so I set out to try and figure this problem out on myself. And the problem was, how long does it take for a person to fall 4000 feet if their terminal velocity is 120?

Here is my process of thought to get the answer... Please correct me when I'm wrong (I know I am)

Height = 4000 feet

Increase rate per second = 32.15 feet

Terminal Velocity = 120 mph = 176 feet per second

So to determine how long it takes to get to terminal velocity...

176 / 32.15 = 5.42 seconds to reach TV

(Or is it 176 / 9.8 squared?)

4000 - 176 = 3824 feet left

3824 / 176 = 21.72 seconds to travel that distance at TV

So 21.72 + 5.42 = 27.14 seconds to fall that distance.

I doubt I am right, but it all seems logical and if I messed up, please correct me, thanks a ton!

Edit: Extremely sorry for not posting it in the homework section...
