Main Question or Discussion Point
In Chapter 8: CentralForce Motion, in the Classical Dynamics of Particles and Systems book by Thornton and Marion, Fifth Edition, page 323, Problem 85, we are asked to show that the two particles will collide after a time ##\tau/4√2##.
I don't have any problems with the derivations and with the integrations, but I want to know please why the authors put a negative sign in Equation (6) and what do they mean that the negative sign was included due to the fact that the time increases as the distance decreases?
Thanks a lot for your help...
