Auto Expert

Responsibilities

As the team expert in automobile kinematics and performance, it is your job to analyze the accident site and determine the velocities of both the SUV and the wagon immediately following the collision.

1. Review the kinematic equations for one-dimensional motion

• Physics Classroom Kinematic Equations
• PhysicsLab Online Kinematics
2. Analyze the diagram of the collision scene below.  Note that the acceleration of a Subaru Outback Wagon with the brakes locked is -3 m/s2, and the acceleration of a Cadillac Escalade SUV with the brakes locked is -2 m/s2.
3. Using the information provided, and looking at just the time period AFTER the collision, find the initial velocities of both the SUV and the wagon prior to their deceleration to rest.  Give this information to your team members.
4. Create a one-page type-written report (including appropriate diagrams and equations) explaining your work and showing your derivations.
