Rectilinear Motion Take-Home Exam - DEAD END!

mizzou0222

Hi everyone.

I'm in crisis mode over this take-home exam I have due in 12 hours. I've posted the 4 problems I'm stuck on and ANY help would be a life-saver.

I can get all of them setup, but am completely clueless as to how to actually execute them.


I have a few questions in specific:

[Question 2] To determine the minimum stopping distance, wouldn't I need to know the mass of the block in order to calculate the normal force and, by extension, the force due to static friction?

[Question 5] ......what?

No. Express the normal force in terms of m. It will cancel.
