okay okay...anyways, I got the answer for B in the first questions. But I still can't figure out the answer for the second one...my friend told me to put it into the equation:
1/2 K x^2 = 1/2 mv^2
and solve for v but I didn't get the answer right...any suggestions??
Nope, that's what I've been looking for till now. I'm doing a research on HOW to relate those equations...What about my other problems? and btw, this is an AP Physics course
A 0.38 kg mass is attached to a spring and executes simple harmonic motion with a period
of 0.08 s. The total energy of the system is 1.9 J. Find:
a) the force constant of the spring. Answer in units of N/m.
b) the amplitude of the motion. Answer in units of m.
For a, I got 2341.655 N/m...
