A slingshot is a Y-shaped stick with rubber bands between the prongs for shooting
stones and other small projectiles. A stone is shot by first placing it in the slingshot
holder, which is attached to the rubber bands. The stone and holder are then pulled
back, stretching the rubber bands. When released, the stone is propelled forward and
leaves the slingshot at a high speed.
Which type of energy transformation occurs from the point when the rubber bands are
fully stretched to when the stone leaves the slingshot?
