How to Build a Tennis Ball Launcher for Science Games Day?

[Osiris_]

Hey guys, I am a year 10 student and I took part in a competition called the Science Games Day...One of the event stated that I need to build a tennis ball launcher that can launch over 10m and 1.5m in height...

There is also a lot of restrictions.

Can anyone help me with this like giving me a design that is good.I being dreaming to win this competition?

Thank you

We can't design it for you.

However, the document link shows several designs on the last graphic:

1) trebuchet

2) air cannon

3) slingshot

Not mentioned is a ski jump that would be unique but it might exceed the 1x1x1m size limitation.

You could also search online to see some examples and maybe search images too.
