    High School What Delta Y Should Be Used to Calculate Viy in a Marshmallow Catapult?

    To calculate the Viy velocity for my marshmallow, what am I supposed to use for delta y? Would it be 0 because my catapult is pulled all the way to ground before I let it go, or would it be the height at which the catapult specifically flings the marshmallow?
