Ok, I understand. EM= U+K U=-8kJ and EM=9kJ 17kJ=.5mv^2 solve for v. Thank you.

Well I know that the the maximum speed occurs when the potential energy is at its minimum. The potential energy is at a minimum at x=5m. I am looking for the maximum velocity but I don't know how to find the kinetic energy at the point.

In a rather bad science fiction movie, astronauts Susie (mass 60 kg) and Fred (mass 86 kg) are investigating an alien probe. All of a sudden, the probe starts to produce a weird defensive force field. Their space ship's board computer scans the field and produces the above plot of the potential...
