in a frictionless vacuum, 45°, otherwise (on earth), aim to have the projectile release when the arm is at about 40° from the base
45 degrees

The [horizontal] range of a projectile is maximised when it shoots at a 45 degree angle. This is true if air resistance is ignored so that the only force acting on the projectile is gravity.
Easy . Think of it like this. The higher you angle your catapult (or whatever your using.) The higher it will travel but it will have less power. If you have a lower angle you will have more power but it your projectile will hit the ground first. If you don't understand just play around with a slingshot and an empty can of soda. Or you could test it out this theory by playing around with angry birds ;)
The difference of these two is that pullback is how far and launch angle is the elevation. I'm not sure but you can check on Science Buddies or just google it .
An acute angle is less than 90 degrees.

You use a catapult to launch things into the air.

A catapult launches an object far by converting potential energy into kinetic energy. When the tension is released, the stored potential energy is transferred to the object, propelling it forward. Factors like the tension in the catapult's arm, the angle of launch, and the weight of the projectile all contribute to how far the object will be launched. Additionally, reducing air resistance and optimizing the design of the catapult can also help increase the launch distance.
The catapult was made to launch projectiles and was very useful in battle before modern warfare.

Build a catapult. Launch things at them.
To launch a large rock by kinetic power.
Hurl, eject, catapult.
To launch a large rock by kinetic power.
As you know best places satellite launch to space is to be equator plane of earth. Because gravity is less than polar. Acording to the Napier rules, your launch angle must be equal latitute angle if you launch a thing to space. Thanks to all.
