Got it! thanks! hadn't tried that with my new velocity. Much appreciated.

Maybe i should try that again, i just got confused on what length meant.

I found that, but what can i do next? I have the length of the string, but i can't seem to find a way to find the wavelength, or the length of 1 1/2 wave lengths.

Find the period of oscillation.

The diagram represents a snapshot of a standing transverse wave on a flexible string taken when the displacement is at a maximum. The string is 1.34 m long with tension 6 N. The total mass of the string is 12.22 g. Find the period of the oscillation. The diagram is unlabeled. it just shows...

Thanks, a lot I got it.. We're learning new stuff fast, so I just assumed we were supposed to use maybe the new Energy equations involving all those little variables. Totally forgot about the simpler equations. Thanks a lot both of you.

A 35.0 kg block at rest on a horizontal frictionless table is connected to the wall via a spring with a spring constant k=25.0 N/m. A 3.60×10-2 kg bullet traveling with a speed of 490 m/s embeds itself in the block. What is the amplitude of the resulting simple harmonic motion? Okay. So If...

Thanks a lot for the explanations, you were right on :)

So what i think now is XXFFT Really not sure on the first two, but i think that C=F D=F E=T

A simple pendulum suspended in a rocket ship has a period T0. Assume that the rocket ship is near the Earth in a uniform gravitational field. (If A and E are true, and the others are not, enter TFFFT). A) If the ship accelerates upward, the period decreases. B) If the ship goes into...

Yay: ) I got it Thanks!

So, Hands are Pivot. Weight of girl*distance from pivot = F* distance of feet from pivot 45*9.8*.65 = (1.66)F F=286.65/1.66 F of feet = 172.68 Only one shot left for right answer.. Does that look good?

A physics student is about to do a pushup. Her center of mass lies above a point on the floor which is d1 = 1.01 m from her feet and d2 = 0.65 m from her hands. If her mass is 45.0 kg, what is the magnitude of the force exerted by the floor on her feet? (Neglect friction in this problem) I...

I got this one, forgot I asked for help. Thanks!

Well that's actually the right answer, thanks. But where did 24.3M_man come from? I was just getting 292M_man, as opposed to 292 +24.3M_man.. Grr I think it was just math, i didn't distribute to the M_man. Thanks a lot for ALL your help : )
