Thanks Tiny Tim! Can I ask you another question? I have an answer I would like to have you go over it for me. Thanks :smile:
Find the equation of motion and the natural
frequency of the system shown (m and k1, k2, and
k3 are known). (Hint: The equation of motion will
have the formx&&...
o.k now I'm more confused than I was before. I was under the impression that I had to use polar coordinates to solve this problem? Where we came up with the fact that r’’ = r(Ɵ’)2…? I attached a photo of the problem. Can we start from the beginning again. There is no tangential acceleration...
So with that being said. I set up my polar coordinates, ur and utheta, and everything in utheta direction (tangentional) equals zero...? Right? Since the velocity u of the bar is constant that is why utheta equlas zero. Then the only thing I have to figure out is the ur direction for...
[b]1. The collar P slides outward at a constant
relative speed u along rod AB, which rotates
counterclockwise with a constant angular
velocity of 2π/3 rad/s. Knowing that r=10 in
when θ=0° and that the collar reaches B when
θ=90°, determine the magnitude of the
acceleration of the collar P...
Homework Statement
An oscillator with a mass of 600 g and a period of 1.20 s has an amplitude that decreases by 2.50% during each complete oscillation. If the initial amplitude is 6.40 cm, what will be the amplitude after 50.0 oscillations?
Homework Equations
How do I approach this...
The figure shows two planets of mass m orbiting a star of mass M. The planets are in the same orbit, with radius r, but are always at opposite ends of a diameter.
This is the equation eq. I used:
mv^2/r=GMm/r^2+Gmm/(2r)^2
This is what I came up with but it is not the right answer. Where...
I'm in a physics 201 course and very confused about the kinematic equations. Is there anybody out there who can describe what each one means?
Thanks,
