Review for test

Here are some questions from your physics book to think about if you want some more practice   The answers are in the back of the book.

p73-80

7, 15, 21, 29, 35, 43, 59, 63, 71, 77, 83

Remember the lab is also due on Monday the 26th.

Oh, and here is a link to a pretty good test (with answers at the end) written by a different teacher somewhere.

AP Lab Two

AP Lab 2 – Projectile Motion.

Your Task:

In this lab you will be determining the initial velocity of a projectile from its range as a function of its launch angle, and then analyzing the effects of air resistance. Roughly the steps will be as follows.

1. Derive an equation for  R(θ, v)
2. Find  a way to manipulate your axes so that a graph with axes based on θ and R should produce a linear graph, the slope of which will allow you to determine v0.
3. Collect enough good data, that you can determine v0 within a tolerable range.
4. Graph and analyze your data, looking for v0 and a description of the effects of air resistance.

As before copy the questions from the link below to your lab document and answer the questions.
