Hi,

I am working with a group of people on a physics project based on projectile 
motion. Our task is to build a ping pong launcher that will launch ping pongs 
into a bin 3.5 to 4.5 meters away from a line. The launcher must be behind 
this line. Furthermore, the ball can only be launched at a maximum of 30 cm 
above ground level. Do you have any suggestions that can help us construct our 
project?
