Homework Help: Push out solenoid force-distance problem

  1. Feb 18, 2014 #1
    I want to purchase a push out solenoid for throwing stuff into air and need help deciding the best one...
    I want to push 4kg of load into air at 90degress starting from rest to a height of atleast 3 metres.
    How much force(in newtons ) would that need ?
    Also if you could explain the method you used to calculate this ?
    Thanks :)

    I can't give much help with this, but I think you should provide a little more information to assist someone who may be able to help. Over what distance can the solenoid be in contact with the object while it accelerates it? Also, what high current power source do you have available to power the solenoid?

    Is this a student project on which you will be graded as part of your college assessment?
