I'm a little under the weather, so enjoy this video introduction on problem solving with the projectile motion particle model. This should be enough to help you get started on the projectile problem worksheet I had waiting for you on the cart this morning. You only need to watch two segments, time 0:00 to 3:00 and time 7:00 to 12:40. Then you can work on the sheets together/alone with your groupmates.
The angled launch stuff picks up around the 12:30 part of the first video, and then carries into this second video.
