The impact of slingshot bullets

The slingshot smashed the glass bottle within 7 meters and made a small hole in the plastic steel window.

The strength of slingshot toys mainly depends on two factors. The first is the rubber band. If the rubber band is thick enough and long enough, the greater the elasticity it can give out. The second is the user's own strength. If the user's power is strong enough, the bullet will be strong enough.

The strength of the slingshot is determined by the elasticity of the rubber band that makes the slingshot. The elastic force of rubber band is f = 1/2kx * x, and according to the formula, the elastic force of rubber band is directly proportional to the square of yield coefficient and elongation. That is, the strength of slingshot is related to the yield coefficient and elongation of rubber band.
