WGU C165 Integrated Physical Sciences Exams Questions with verified Solutions 2024/2025 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 transf...
