**1. Homework Statement**

Car: mass = 200g

Moving at 30 m/s

Braking force of 10000N.

How far does the car travel before stopping?

**2. Homework Equations**

W=m x N

w = F (delta x)

**3. The Attempt at a Solution**

I found work, (2000)(10000) = 20,000,000

Then rearranged the second equation to get delta x, and got 2000 as my answer. The answer is 90m and I'm not getting it. Any suggestions?
