Ideal Ball weight to get the maximum range from a ball launcher?

AI Thread Summary
The discussion focuses on determining the ideal ball weight for maximizing the range of a ball launcher designed to propel a line of baits into the sea. Aiming for a launch angle of 45 degrees, the user has created a simplified model that currently shoots a soccer ball (1 lb) about 100 yards without any line or baits. The weight of the line is also approximately 1 lb, with baits spaced 10 feet apart. It is noted that while heavier balls can reduce air resistance, the optimal weight depends on the launcher's specific design and velocity characteristics. Understanding these factors is crucial for achieving the desired distance.

Hello guys, i am building a ball launcher to proper a line of baits into the sea, the line has 25 baits, each bait weights 30 grams (about 1oz)

ideal shooting degree seems to be 45 to get maximum range, What I would like to figure out is the ideal weight of the ball to achieve the greatest distance for a shot.

Here is an illustration of what I want to do:

Many thanks for helping me with this.

If this is an attempt to design such a device, perhaps start with a simplified model to get a feel for the problem?

You don't mention the weight (better: mass) per unit length of the rope to which the baits are attached. Nor do you define the spacing of the baits on that rope.

Why not simplify the initial attempt by assuming a uniform rope of constant linear mass per unit length that effectively includes the masses of the baits along its length?

I think that this simplified version of the problem will not be an easy task to analyze, even ignoring air resistance on the line and ball.
 
Hi Gneill,

Thank you for your reply, I actually already made a simplified model, I am currently able to shoot a soccer ball (1lbs) about 100 yards, with no line or baits attached to it, that distance should be improved in the future real thing with a better band and design.

The Weight of a line (very thin rope) of 100 yards is about 1lbs too, the spacing between baits is 10 ft.

I thought about air resistance too, but as I am a complete newbie when it comes to physics I have no idea how to do the calculations.

Thanks again for helping.

A lot of this depends on the details of the launcher itself. If the launcher always launches at a fixed velocity, ideal ball weight is as heavy as possible to minimize the impact of air resistance. However, all real launchers will have some sort of launch velocity dependence on the mass of the projectile, and you need to know this before you can have an answer.
 
Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
