Homework Help: Projectile Motion experiment

  1. Nov 9, 2015 #1
    [mod note: post moved into homework forum, so template is absent]


    I have an open ended investigation to do for school, and was wanting to do an experiment involving the motion of water from a hose, as this would give me a good parabolic curve to view. I wish to examine two independant variables. First one is angle of launch - pretty easy. I'm having trouble with a second one through.

    I was wondering whether i could change the pressure of the actual tap/ hose, and whether or not this has any correlation to initial velocity, as in can I work out the initial velocity if I measure the pressure of the tap using a pressure gauge, for example.

    Any help on the topic would be much appreciated. Cheers.

    Hi Bucko. :welcome:

    Sure, the more water that passes through the hose per second, the faster its velocity. So the problem becomes: how to calculate or measure that exit velocity.

    Any ideas?
