Question

A sky diver jumps from a reasonable height above the ground. The air resistance she experiences is proportional to her velocity, and the constant of proportionality is 0.2. This can be shown that the downward velocity of the sky diver at a time “t” is given by the equation:

v(t) = 80(1 - (L^(-0.2t)))

a) Find the initial velocity of the sky diver in (ft/s).
b) Find the velocity after 5 seconds, and after 10 seconds.
c) The maximum velocity of a falling object with wind resistance is called “terminal velocity” (which means that can´t incincrease any more); determine the “terminal velocit

Answer 8

Okay, so tell me that when something is STARTING (initial), what's the time?

Answer 9

?

Answer 10

0

Answer 11

YES!
So for part (a), set t = 0.
