At point D, you have KE and PE, so at point E, the KE will be increased by the change in PE from D to E. Now that you have the KE at E you can find the velocity at E.
Just before E, the weight will be the sum of the centripital force as determined by the velocity you calculated above + mg. Just after E, the weight will be only mg. Now kowing the velocity, you can probably fined the distance to stop.
Did you get the velocity at D?
