No, there's no difference between the magnitude of the tension in problem 1.
As for the acceleration, in those problems, we are supposed to find:
normal force
tension
acceleration
Masses will be given, as well as coefficient of friction (only kinetic friction).
As for equations, that's where...
Hello,
I am taking intro Physics and we are having a little quiz this friday. Professor gave us handouts and told us to solve them by ourselves, and then study those problems because the same problems will be on the quiz. Now, my problem is, is that I really don't understand the subject...
Problem 1:
The position of a body moving on a coordinate line is given by S = t2 - 4t + 4, with S as meters and t as seconds. When, if ever, during the interval 0 <_ t<_ 4 does the body change direction?
Here I just don't know how we get from "S = t2 - 4t + 4" to "V=ds/dt = 2t - 4...
I am posting here because this is NOT homework. Problems are finished. However we have an exam on friday for calculus 1 class and well... I've been trying real hard to understand it but professor has a real strong accent and he speaks too low, no one can hear a thing!
Anyway, we did the...
