Two identical point charges are fixed to diagonally opposite corners of a square that is 0.510 m on a side. Each charge is 3.03 10-6 C. How much work is done by the electric force as one of the charges moves to an empty corner?

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
