Question

What is the speed of the airplane as a function of time?( Physics )

Answer 1

`v(t) = v_i e^(- B/m t)`

Explanation:

The integration yields:

`ln |(v(t))/v_i| = - B/m t`

Or:

`v(t) = v_i e^(- B/m t)`

NB: note the slack use of the word speed. We are actually talking about a velocity here.
