    How High Will a Pebble Go When Shot from a Compressed Spring?

    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!
