What is the best way to launch a golf ball 4.5 meters exactly using a mousetrap?

We are doing a project where we have to launch a plastic golf ball exactly 4.5 meters using a cheap $1.50 mousetrap and we are looking for suggestions as how to achieve exactly 4.5 meters.|||You can adjust the trajectory to achieve 4.5 meters.





The formula is: distance = (v虏 sin 2肖) 梅 g





Where:


v is the initial velocity of the golf ball


肖 is the launch angle


g is the acceleration due to gravity





A 45掳 launch angle produces the greatest distance. As long as you can get 4.5 meters (or more) with 45掳, you can adjust the the launch angle to get the ball to land exactly at 4.5 meters. The trick is getting a consistent initial velocity and avoid veering to the left or right.





30掳 and 60掳 will travel the same distance on the fly. The 60掳 angle just produces more of a lob. I suspect you have a bucket or other target to shoot for.|||Drill a hole in the golf ball and fill it with some material (sand, water, etc) to increase its weight. Of course you have to be able to tape up the hole afterwards so that whatever material you stuffed it with stays inside.
