## The Attempt at a Solution

This isn't really homework, but rather just some self study to help me understand some of my work better. Attached is the answer.

*My real question in this case is some info on how the dot product works? Been trying to find some info about this for 2 days now. If someone could just help explain the dot product between a and 2M, I would be really greatful.*

Thanks
