**A driver travelling at [tex]30\ ms^{-1}[/tex] slammed on the brakes when a truck pulled out ahead. The skid marks leading to the wreckage are [tex]40\ m[/tex] long. Tests on a similar model car show the brakes provide a steady deceleration of [tex]6\ ms^{-2}[/tex]. How fast was the car travelling when it hit the truck?**

**I'm not sure how to go about solving this problem, so any help will be greatly appreciated.**

**Thanks**
