Week of 11/7

I had one student come into my office hours this week. She had a question about an example from the previous week's Powerpoint slides regarding power and friction. I helped simplify the problem by pointing out that the goal of the problem is to only find the work of friction as a block slid down a ramp, and this is the component going in the same direction as the slope of the ramp. After we found the normal component of the weight of the block, she was able to apply the power equation to help her solve the problem.
