[QUOTE="Jake357, post: 6856544, member: 733578"] [B]Homework Statement:[/B] Two small bodies have a mass of 0.009 kg each and are tied together with a wire that has a length of 2m. The bodies have the same electric charge of 5*10^-6 C each. The charges are on a horizontal surface. The wire gets cut. Calculate the distance travelled by each body till they stopped and the maximum velocities that they had. Calculate the distance between them at the moment they were having the maximum velocity. The coefficient of friction between the bodies and the surface is 0.1. The the distance travelled by each body till they stopped must be 5.25 m. The maximum velocity that they had must be 0.67 m/s. The distance between them while they are having the maximum velocity must be 5 m. [B]Relevant Equations:[/B] Wf (the work of friction)=μmgd We (work of the electric potential)=kq^2/d I only could calculate the distance travelled by each body, by making the difference between the initial and final electric potential work equal to the work of friction done by the 2 bodies.
