Understanding vectors will be important in physics 6c. Here is the solution to one vector problem; I think this is from one of the first homework sets. I believe there is also a video solution to this problem linked in an earlier post on this blog. (link also added below in this post)
You may go through the earlier posts on this blog from last Spring, if you like, and find solutions to other vector problems we did (for example, in the post "Homework 3. due Friday" from April 16). Feel free to share your knowledge, insights and questions with other students by posting here about what you find.
Below the break there are some video solutions to vector problem from 6a.
