And from there you could calculate the final velocity by running it back through the kinetic energy formula, right?

I think so... it would be something along the lines of KE - Wf = KEnet, correct?

Oh wait I just realized that there is an equation for the work done by friction: W = -F*d

(There is no template for the problem. It is given to me in a text form.) The kinetic energy decreases as the vehicle passes through the mud due to the lowering of the velocity... I know how to calculate the kinetic energy of the vehicle before it enters the mud. I just don't see how the...

There's no template included. Equations that I think might be helpful: Work = m*a*x Kinetic Energy = .5*m*v^2 Kinematics equations

The problem is asking me to find the final speed of a 1100 kg car traveling at 24 m/s through 18m of mud, where the resistive force on the car is 17000 N. I don't actually know how to go about doing this, so any pointers in the right direction would be super helpful.
