Consider a body of unit mass freely from rest under gravity with velocity v. If the air resistance retards the acceleration by cv where c is a constant, then
1
\(\rm v=\frac{g}{c}\left[1+e^{c t}\right] \)
2
\(\rm v=\frac{g}{c}\left[1+e^{-c t}\right] \)
3
\(\rm v=\frac{g}{c}\left[1-e^{-c t}\right] \)
4
\(\rm v=\frac{g}{c}\left[1-e^{c t}\right]\)
