never mind, I am a little special

what equation did you use to find left and right?

could you explain how you went about doing this problem? I am a little lost

Homework Statement Suppose we make a circular hole 4 millimeter in diameter in a balloon. Calculate the initial rate at which oxygen escapes through the hole (at 0° C), in number of helium atoms leaving the balloon per second. Homework Equations # of molecules/second =(1/4) (Number of...

Oh I figured out why it was wrong, its supposed to be the mass of one atom, not one mole. so m = .207/6.02e23 E=hbar*sqrt(20/m) E=8.0427e-22 J

Homework Statement the stiffness of the interatomic "spring" (chemical bond) between atoms in a block of lead is 5 N/m. Since in our model each atom is connected to two springs, each half the length of the interatomic bond, the effective "interatomic spring stiffness" for an oscillator is 4*5...

I used the center of mass. The CM moves .07 and the amount of force applied is 8N, so the work done is .56 Joules, and since the initial KE is 0, the final KE is .56J. Oh i accidentally put the wrong trans KE...

Well there isn't any equation for finding the vibrational energy in my book, but this problem had a first part to it where it asked for the the translational kinetic energy for the blocks as a point particle system, which doesn't have the vibrational energy, which i found was the same for both...

Thanks! I found the work to be .64 joules and i used W=deltaK, but this gives me the total kinetic energy, and I'm trying to find the two different kinds of kinetic energy, Translation and vibrational.

Homework Statement Moving blocks connected by a spring Two identical 0.13 kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring whose stiffness is 225 N/m, as shown in the upper diagram. Then a constant force of 8 N to the right...
