Homework Practice

The information we know and the thing we want to know (our goal) are all listed in the image below and at the right. Our list of some accelerated motion formulas is shown below and on the left. Remember: When trying to decide which equation to use, we should try to find an equation which contains only those things we know and whatever we are looking for.

Use our known variables and our goal below and at the right to choose which equation we should use from the list below and at the left. Then, complete the self-quiz at the bottom of the page to find out which is the best equation to use to solve our problem.
