#### Identify What is Asked

You cannot solve a problem if you don’t know what is the problem.

Michael is driving his sports car at 30 m/s when he sees a dog on the road ahead. He slams on the brakes and comes to a stop in 3.0 second. What was the acceleration of Michaels’s car?

What is asked in the problem? It is the acceleration of the car that Michael is driving.

#### Recall Concepts and Identify the Formula

*Acceleration = Final Velocity – Initial Velocity / Time*

#### List the Given Values

Initial Velocity = 30 m/s

Final Velocity = 0 m/s *since the car came to a stop*

Time = 3.0 s

Acceleration = *unknown*

*
* Now you know that you are given with three values in the formula and the Acceleration is the only one unknown to us.

#### If More Variables are Unknown, Solve them First

This is a common

*problem*in problem solving. For example, you might be asked to find the Torque of a rotating stick but you are only given with the mass that makes it rotate.

#### Solve the Problem Using the Formula

Now that you have all the variables except the one unknown, you can solve for the answer.

#### Practice Makes Perfect!

#### State the Answer to the Problem

*Therefore, the acceleration of the car is -10 m/s2.*
