I need help with Conservation Laws!

The question I'm doing for homework that I can't get is...

A spring is compressed 10.0 cm by an average force of 50.0 N. If the spring shoots a 20.0 g pebble straight up into the air, how high will it rise?

It would be sooper awesome if you could help with this!

Where did you get stuck? Show your work to get help. (Hint: Spring PE gets transformed to Gravitational PE.)
