You were right in that it was a problem with the number of significant digits used. The homework is submitted online and the site used is a bit touchy. Thanks

My first homework assignment for griffiths is underway. Here is a problem I can't figure out. Q. Two identical conducting small spheres are placed with their centers 0.350 meters apart. One is given a charge of 12.0 nC and the other is given a charge of 16.0 nC The spheres are...

thanks, i was skeptical of that approach but it worked out after a mess of algebra and a quadratic equation to solve

Here's the problem: An atom of mass 2mp with an anitial velocity vo undergos an elastic collision with an atom at rest with mass 3mp. After the collision, the first atoms trajectory deviates 30 degrees from the initial. What angle does the second atom travel from the first atoms initial...

thanks a lot, i worked it out

I am not quite sure how to start this problem: A bullet of mass m is fired from a gun of mass M. If the gun can recoil freely and the muzzle velocity of the bullet is v. Show that the actual velocity of the bullet relative to the ground is v/(1+b) and the recoil velocity from the gun is...

i don't know if you (statusX) tried to solve these... i am getting an imaginary answer for x (x=iwt). i haven't solved for y(t) yet. Isn't the imaginary answer somehow equivalent to a trig function? Does anyone know? thanks

thanks, ill try this out

I'm stuck on this problem: The initial conditions for a two-dimensional isotropic oscillator are as follows: t=0, x=A, y=4A, v=0i +3wAj (vector) where w is the angular frequency. Find x and y as functions of t. Where do I even begin with this problem. I take it A = constant. Can anyone...
