In the attached position versus time graph what is the magnitude of average velocity for the entire 19 seconds of the motion. Answer in m/s and the number only to the nearest 100th (ie. The second position after the decimal point.). Remind yourself of the definition of velocity.

An electron and a proton are held on an x axis, with the electron at x = + 1.000 m and the proton at x = - 1.000 m. part a how much work is required to bring an additional electron from infinity to the origin? express your answer with the appropriate units. part b if, instead of the second electron coming in from infinity, it is initially at x = + 20.00 m on the axis and is given an initial velocity of 100.0 m/s toward the origin, does it reach the origin? part c how close to the origin does it come?
