the actual answer was Af=Ai/√2 when I talked to my teacher.

I not sure how to calculate the time it would be at half energy and I had that thought too. I do not have mass and I am starting with the amplitude of the oscillation. I have been reading my book back and forth trying to figure this one out. Energy does not depend on amplitude. Amplitude...

That looks like I would complete the square of the term under the square root to get something to match arcsec or arccsc. 1/(u √ (u2-a2) is the one I believe i am thinking of..

Homework Statement A mass on a long elastic cord oscillates with an amplitude of 23 cm. If the energy of this system is reduced by fiction to half its value, what will be its amplitude? Homework Equations Looking though my book or resources on the internet have not revealed a path for this...
