Chapter 4 Review

In looking at the Chapter 4 Review, there are 2 problems that you may want to skip and come back to later.  They are #4 and #7.  I apologize that #7 is not very well written.  It should say that a "car is traveling at 50.0 km/h on a flat highway on a rainy day when the driver puts on the brakes."

Here are all of the answers.  We will go over them on Thursday.
