Xpult




 * 1) Name the four different variables we tested using the Xpult? **

We tested the launch angle, pull back angle, # of rubber bands, and the two different ping pong balls.


 * 2) What exact variables seemed to help you shoot the ball into the bucket? **

The exact variables we used were 55 pullback angle, and 60 launch angle


 * 3) Would and Xpult be an example of a first class, second class, or third class lever? **

I think it would be a Third class lever. That is because it has the fulcrum is at the pivot, the effort is where the rubber bands are located, and the load is at the end. The third class lever does not magnify the force, but changes the direction of the force.
