Yeah since energy is conserved minus friction , the total kinetic energy of the projectile at the top of the sling must be less than the total potential energy of the counterweight when it ' s loaded up . Conservation of energy is awesome because we don ' t need to consider how long something takes to accelerate , just to end result how much speed it gained <| sep |> Maybe the first few times it does , so long ago I don ' t really remember .
