Thank you so much, for taking the time to work out all of these problems! I was confused on how to do this problem, and your step-by-step process helped a lot! God bless you!

This was a very good video and I'll tell you why. You came from a student's perspective and came with the tools that a student has, not from the perspective of a professor; from experience and know how. It made me see how I can view this problem with the very basic tools I have already been using; which I think has been the harder part of physics. Thank you and great job!

Thank you very much. AP Physics is so hard!!!

Do you have a video showing how to work the problem using the formula you gave? I wanted to test it out but unfortunately, I kept getting the wrong answer (to problem 42) and was wondering where I kept going wrong.

[hehehaha]

why cant we use the rx = (vi^2 * sin2x)/g formula here
