Homework Statement
A mass m has a velocity Vo at time t=0 and coasters along the x-axis were the drag force is f(v)=-cv ^3/2 find v in terms of t and the other given parameter. at what time will it stop.
Homework Equations
F(v)=m dv/dt
The Attempt at a Solution
So i started by using separation of var and got dv= f(v)dt/m then i just take the integral of both sides Is this correct? then i just do it from 0 to t to one side and 0 to v to the other? How would i then find what time it would stop? set v = 0 or something?
Thanks
