1. The problem statement, all variables and given/known data Given the one-dimensional retarding force F=-Ae^(-[tex]\alpha[/tex]v) find an expression for v(t). 2. Relevant equations F = m(dV/dt) A and [tex]\alpha[/tex] are constants, v is instantaneous speed. 3. The attempt at a solution Im not sure how to frame the idea of integrating a velocity dependent force. Can I take simply integrate and use v= -Ae^(-[tex]\alpha[/tex]v)t or should the v be eliminated from the right hand side. I tried doing that by dividing the left by e^(-[tex]\alpha[/tex]v) and then doing a e^u du type integration but the answer i came up with didn't seem reasonable. just looking for a little hint or push here, thanks!
