That's a different approach than what I was trying. How would I find w though from that information? There's something I'm missing on this question. I can do all the others that go along with it, just not this one. so frustrating...

Help! Planetary motion Please help! Planet X rotates in the same manner as the earth, around an axis through its north and south poles, and is perfectly spherical. An astronaut who weighs 946 N on the Earth weighs 920 N at the north pole of Planet X and only 854 N at its equator. The distance...

Please help! I'm having trouble understanding this rotation problem. At a time 2.60 s, a point on the rim of a wheel with a radius of 0.240 m has a tangential speed of 50.0 m/s. as the wheel slows down with a tangential acceleration of constant magnitude 10.7m/s^2 . At what time will the...

Ok, I guess I should just think of it more that the second derivative is acceleration...

I have a physics problem that I'm stuck on! Its a position vs time graph of harmonic motion of a horizontal mass/spring system. The question is "where is the acceleration greater than 0?". The graph starts at point A (at the origin), goes to B (above the x axis), down to C (on the x axis), down...
