Awagon is accelerating down a hill. which statement is true? question 17 options: the potential energy decreases and the kinetic energy increases the potential energy and the kinetic energy both increase the potential energy and the kinetic energy both decrease the kinetic energy decreases the thermal energy decreases

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?
