Projectiles Fired at an Angle - The Concepts

So here is the presentation I showed you guys today. Check it out again to refresh yourself. This part of projectile motion is challenging if you don't understand the concepts. Once you do, the math is easy.

Projectiles Fired Horizontally Help

You have a quiz tomorrow (Tuesday, 10/28) on projectiles fired horizontally from some height. I have assigned some questions in your "Problem Solving Exercises in Physics" text: page 25, Exercises 11, 15, A-9, and A-11. The answers are in the back of the book (page 294) so you can check your answers.

I have included some links below to help you review before the quiz. Also, click on the link from the last post to practice solving problems.

Projectile Motion

Hey all. We are talking about projectile motion in class these days. Here is a great website to hone your projectile motion skills:

For now, just raise the cannon so that it shoots horizontally. Later we'll fire projectiles at an angle.
