Homework Statement http://i.imgur.com/ITrJq.png Homework Equations F=kq1q2/r^2 (Coulomb's Law) The Attempt at a SolutionWhenever I try to get the answer, I keep coming up with 15.47cm. I found the Coulomb's law for the third particle in relation to the other two, then set those equations...

See, I thought it would be straightforward, but I'm getting a very weird answer, with a lot of square roots and such. My answer for V4, which is the velocity of the second object after the collision, was: sqrt(v)*sqrt(sqrt(v^2-2)+v) When it should be some nice number like 1/4v. I don't...

Homework Statement Let two particles of collide in a perfectly elastic collision. Particle 1 has a mass of 2m, while particle 2 has a mass of m. Particle 1 has initial velocity v, directed to the right, while particle 2 is at rest. What are the final velocities, v1 and v2, of particle 1 and...
