LMC - Car Safety and Impulse-Momentum Theorem Discussion

Respond to the discussion below. Answer all parts. Respond to two other students' responses. 

Do some research on safety features designed into modern cars.  Cover the following points in your discussion post.

• Which safety device do you think is the most important?  Why?
• Explain, in terms of the impulse-momentum theorem how this safety device works.
• People often explain these devices in terms of absorbing energy or force.  How is that concept incorrect when discussing a collision.
