## Homework Statement

A 1100kg car is traveling at 24m/s before it hits a 18m patch of mud with a 1.7 x 10^4 net horizontal resistive force. What is the cars speed as it leaves the mud patch?

## Homework Equations

Change in Uint= fd

KE= 1/2mv^2

W= Fd

## The Attempt at a Solution

1/2mv^2 = f(mud on car)d

1/2(1100)v^2 = 1.7 x 10^4(18)

V= 23.6 m/s

I'm pretty sure this isn't correct, because the resistive force is too great to have the final velocity change only slightly. I feel like I might need to incorporate work or the initial velocity into my equation, but I don't really know how.
