Ok that makes sense ;), but I am still don't know how to do that given this information.

Homework Statement The atomic mass of tellurium is 2.12×10-25 kg, and the frequency, 7.53×1012 Hz. What is the effective force constant that connects the two atoms? Homework Equations Have no idea The Attempt at a Solution I am lost with this problem, we havn't learned it in...

0 I guess, I don't understand how that helps

Homework Statement An object of mass m=2.2 kg is traveling on a horizontal surface. The coefficient of kinetic friction between the object and the surface is µk=0.2. The object has speed v=0.57 m/s when it reaches x=0 and encounters a spring. The object compresses the spring a distance d/2...

I got the answer, thank you so much

Ok but what do I do when I have the potential energy in each spring, add them together or subtract them?

I have tried the question using your method but I am still not getting the right answer:(

Oh thank you, um when I said the missing side I meant that I made a triangle out of the x PE and the Y PE because I thought that the X component of PE on the left was bigger so it would cancel the right out. I will try your method thanks.

Homework Statement Identical, massless springs, with spring constants k = 20 N/m, are connected in series, as shown. The springs are attached to rigid supports at x = ±L, where L = 59 cm. The equilibrium length of the springs is much smaller than the stretched length and can therefore be...
