Physics 16 Simple Harmonic Motion (10 of 19) Find Amplitude=?

In this video I will find the A(amplitude)=?, given k=800N/m, m=2.0kg, and at t=0s, x=0, v=5.0m/s using the energy equation.

I don't know where I would be in life without you and your awesome videos! Thank you so much, sir. :)

thank you so much!! this video was super helpful

[brandond]

thank you so much I'm very worried about my final unit test for ap physics. I have no idea how I'm doing well in that class

I still do not understand what is wrong with using this equation : A = -v/wsin(wt) from the equation v(t)-Awsinwt

This is so helpful! Thanks for this, sir!

Sir, is A the initial displacement of the spring before you let go?

Thanks for the explanation. Can you conlcude from the energie equation that;

Vmax (since t=0) = sqrt(K/m) * A?

If so, you can use this equation to solve any K, m or Amplitude related problem as long as t = 0?
