## Homework Statement

turning on the engine of a motorboat (v0=0),

K = constant force due to the engine

drag force of the water D = -cv

find v(t)=?

## Homework Equations

integration

f=ma, a=dv/dt

## The Attempt at a Solution

[/B]

D+K = MA

K-cv = MA

(A=dv/dt)

K-cv=Mdv/dt

Mdv=dt(K-cv)

?

i want to do integration on both side of the

equation but I can't isolate V

thanks
