We've covered this material in class, now it's time for you to review this and make sure that you understand what you know and what you don't know.

What variables are involved in accelerated motion problems?

Order the choices below to match the process of solving a physics problem

list the knowns and "solving for" variables
solve
sketch a diagram
read the problem
choose the right equation
substitute the known quantity into the equation
solve the equation for the correct variable

A lot of times in solving problems, people think that they have to know immediately how to solve the problem all the way through; before they have even really finished reading the problem.
When you do come across a problem, you have to make sure that you know what you know and you have to make sure that you have all the pieces of information from the problem. So take your time; don’t feel like you have to do everything at once, or that you have to know the immediate answer.  This is not a pop-up question, this is not a Jeopardy question where people just know the answer.
These are types of questions where you have to figure out the answer. So take your time.

In the question below, identify the known and "to solve for" variables. Create a list that shows the variables and their measurement. You are not being asked to solve this question.
If a plane takes off from a 950m long run-way at an with a velocity of 64m/s, what is the minimum acceleration required to safely lift off?

In the question below, identify the motion variable which is not a part of the question and then decide upon and list the equation necessary to solve this problem. For an extra point, solve the equation for the correct variable.
