Homework Help: Spring launcher

  1. Dec 4, 2003 #1
    i need to make a spring launcher that launches a small ball using a spring (one that stretches)... so how do i attach the spring to the piece of wood so when i stretch it all of the energy is converted to the ball..

    Well for a start off your request is an impossibility - you can't transfer ALL of the energy to the ball, only a proportion dependant on the efficiency of the system.

    Secondly you say "how do I attach the spring to the piece of wood " Well this does rather beg the question... What piece of wood?
