Homework Statement:

A boat of mass m with initial velocity v_o is slowed by a frictional force
F=bexp(αv), α and b are positive constants .
Relevant Equations:
 F=bexp(αv)
The photo above is the problem I'm struggling now and the photo below is what I have done so far.
By differentiating and integrating the given equation, which is F=b exp(αv), I tried to express v(t) or a(t) as a function related to t, which is time.
But the more I did, the more complicated it got...
Force is related to the velocity so when you differentiate it, the acceleration function about t comes out so you cannot just express its motion.
How was I supposed to approach this problem to?
Look forward to hearing from you guys.
Thanks a lot!
