A simple harmonic oscillator has spring constant k= 4.2 N/m , amplitude A= 13 cm , and maximum speed 4.2 m/s.

What's the oscillator's speed when it's at x= 5.2cm?

with v you can do many things
since you have k you can use the formula v=omega/k to find omega

anonymous · Answer

are you looking for an equation like this:
x=Asin(omegat+phase constant) ?

anonymous · Answer

umm i think its this equation....$$v= \sqrt{\left(\begin{matrix}k \ m\end{matrix}\right)} (A^2-x^2)$$

anonymous · Answer

but when i pull everything together the answer is not correct

anonymous · Answer

ive never seen taht before tbh LOL

anonymous · Answer

oh sorry its max speed and not wave speed

anonymous · Answer

ok, so v=Aomega
you can get an omega

btw speed is -
