How do you make a tool with messed up physics that slightly launches you when you jump?

i was playing old roblox games earlier with a friend and we found a tool in an old game called “net”
when you jumped with it, youd jump high and get launched a tad bit forward, and i want to figure out how to recreate this
the high jump part is easy, i just dont know how to mess up the tool’s physics to launch the player

try when you equipped the Equipment,
and listen to humanoid state changed event
if it is changing into Jump, you add a velocity to the humanoid root part AssemblyLinearVelocity
