I noticed that too — If you click on the QR Code, the answer is dragged over and explained via video — FYI.

Hello John, How would you approach answering #87, parts (c) and (d). I have completed the others but am stuck on this one. Much appreciated.

Manuel, The key is to use the FBD for Block B and Block C. The friction force pulling block C is equal in magnitude to the friction force that C acts on B as explained by Newton's Third Law. Use the C equation to find the friction force, and input it into the B equation, where a = 2, and solve for mu. Once you have mu, you can solve part (d) by using the FBD for block C. I'll email you the complete solution to check to see if my hint was any good! John
