Also, I have a ton more questions
Where do you use that formula for the v^2, how did the thing for the horizontal motion work, it was way too fast, and what did delta x mean, along with just x. If delta x is displacement, what is x? Is it a position or something? Why did we have 2deltax in the last equation? Why is that a difference of squares? How do you use the vector thing in equations? How is displacement area and also that line in a vector? How did you get -44 when the question said 22 and how did you get the time after that? This is super confusing, and I'm probably going to be more confused when I do the problem set. Was that line resulting from a vector or displacement? Why does the addition rule work? I thought two sides of a right triangle squared were equal to the hypotenuse squared? Does the addition rule work for displacement only? Why? This is P1
ok thanks
