if your are aware of the MacGyver projects at VA Tech i only have a small amount of materials to use so if you could please tell me how or what you would use in this situation
Thankyou

Easy. You'll need a couple of equations and a basic understanding of Calculus.
First, F=ma where Force = mass x acceleration.
Something must push or strike the ball and you will need to know how much force is to be applied when it does. You will also need to wiegh the pp ball and solve for acceleration. With this you calculate the balls initial velocity with:
v^2=2ax v=velocity, a=acceleration x= how far away the bucket is.
After you know velocity you need to know at what angle to shoot it - Theta=arcsine (gx/2v) g=gravitational constant.
Now you can hit the bucket. Your problem is measuring with what force the ball is hit and deciding what to hit it with.

Elastic bands are a winner.
I'd recommend setting up a slingshot system, all the parts held carefully in place with a metal clamp framework (set up like a U to hold the twined elastic bands across a gap)... and to give the ball a launching runway (like a ruler or something through the base of the U on which the ball is placed) to ensure that its force is applied in the correct direction.
Provided everything is held in place precisely, and you can do a few test-runs with the elastic bands and whatnot to check sufficient force is applied to the ball, its subsequent relative speed along the runway (measure out a particular distance in a straight line, preferably through the air to minimise friction, fire it across the distance and time it to ascertain the horizontal component of its velocity) and the point at which it becomes subject to gravity (acceleration of 9.81m/s^2 downward)... you should be able to calculate the precise trajectory it will take and put the bucket there.
Of course you could skip out the mathematics altogether and just set it up... fire a few times, and put the bucket where it lands... provided its consistant. It should be.

Get a mamber of the basketball team and tell him it's just like shooting free throws.
