Don't know how to start it please help.

I am stuck on this question please help.

Please help with this question and how to set it up.

I have been using the equation Kq1q2/r and have been making 0.15nm 1.5x10^-10 and q = 1.60x10^-19. the answer is 1.39x10^-17. I can't seem to get this answer. Thanks.

All they gave me was the height if 5m and the speed when it hit the ground of 4.5 m/s. The object was at rest at the top.
