Vectors and Scalars.... Oh my!

Hey guys!  Here's today's physics lesson.  Your homework can be found here.  Please print it out and bring in a copy for yourself.  If you find some of the problems challenging, don't be surprised... this is tough stuff!  Next week we will be (finally) getting around to our Egg Drop, so make sure you bring in your egg saving device.  Remember the rules:

1. No Balloons or materials lighter than air
2. No rockets or electric motors
3. The total value of your device can't be more than 10 dollars
4. Justin will drop the eggs and devices.
5. A cracked egg beats a smashed egg, but an unscathed egg is best.
6. The lightest device that is completely successful wins.
