    Non-Uniform Circular Motion Problem

    I did mean angular acceleration by the "a" in my equation, I just don't know how to make the symbols. If the approach I have taken isn't correct, what else would you do?

    Non-Uniform Circular Motion Problem

    Homework Statement A car starts from rest on a curve with radius 150m, with an acceleration of 1.8 m/s2. How many revolutions will the car make before the magnitude of its acceleration is 2.40 m/s2? Homework Equations at2 + ar2 = total acceleration2 theta = omega (t) + .5...

    How Do You Calculate the Y-Component of Velocity in a 2D Kinematics Problem?

    It actually an online site that we do our homework on, I found those graphs elsewhere. I know it has something to do with the acceleration of gravity, but I submitted the answer 40 and got counted wrong (i submitted both negative and positive

    How Do You Calculate the Y-Component of Velocity in a 2D Kinematics Problem?

    Homework Statement A particle starts from rest at (r0) = 9m j-hat and moves in the xy-plane with the velocity shown in the figure . The particle passes through a wire hoop located at (r1)=20m i-hat, then continues onward...

    One dimensional motion problem, overcoming head start

    that is the actual question, my inability to distinguish letters was the problem, thanks for the help wow, I feel dumb. My homework is entered electronically online, and I was actually putting the wrong variable for the velocity of the two cars. I was entering the greek letter nu because I...

    One dimensional motion problem, overcoming head start

    I know this problem has been posted before, but I think my answer is correct and I want to know why it was considered wrong! Homework Statement Cars A and B are racing each other along the same straight road in the following manner: Car A has a head start and is a distance Da beyond the...
