A car strikes a wall traveling 30. mph. The drivers cervical spine (basically the neck) first stretches
Question:
A car strikes a wall traveling 30. mph. The driver’s cervical spine (basically the neck) first stretches forward relative to the rest of the body by 0.010 m and then recoils backward by 0.020 m as shown below. Assume the spine can be modeled by a material with a modulus E = 10. GPa and a strength of 1.00 x 102 MPa. Will the maximum stress on the cervical spine during this whiplash portion of the accident exceed the strength of the spine? Assume a 0.15 m length of the cervical spine.

As a tutor, I have gained extensive hands-on experience working with students one-on-one and in small group settings. I have developed the ability to effectively assess my students' strengths and weaknesses, and to customize my teaching approach to meet their individual needs.
I am proficient at breaking down complex concepts into simpler, more digestible pieces, and at using a variety of teaching methods (such as visual aids, examples, and interactive exercises) to engage my students and help them understand and retain the material.
I have also gained a lot of experience in providing feedback and guidance to my students, helping them to develop their problem-solving skills and to become more independent learners. Overall, my hands-on experience as a tutor has given me a deep understanding of how to effectively support and encourage students in their learning journey.
