Hi there, You might hate me for this as I'm completely new to physics.
My university has me taking a side course in Introductory physics. This would be ok if I knew a little about the subject, but I do not. So I'd love for some help with the following:
I have been given the task to work out the force needed to push in with a mass of 5kg and pull out on a simple hand pump (pic included). Whilst taking into account the friction when pushing in.
[PLAIN]http://www.awcycles.co.uk/images/blackburn/mynAir3.jpg [Broken]
Now I am not asking for this to be done for me. All I'm asking is just some help on how I start the equation/formula. As I am unsure where to start.
Any help is apreciated. Many Thanks.
