    The spring imparts the same amount of energy to the marble and bowling ball. The two objects are not at the same velocity, the marble would be moving significantly faster.

    The same velocity doesn’t necessarily imply the same amount of kinetic energy right?

    Not at all.

    E = 1/2mv^2

    Since energy (E) is provided by the same spring in both cases, the energy of the bowling ball and the marble are equal. Since mass (m) is much higher for the bowling ball, the bowling ball’s velocity (v) must be significantly lower.

      That’s why I’m stupid! End of shift sleepy brain forgot about the parent comment talking about the spring because of the confusion about velocity. Seems so silly to forget a piece of the conversation while I’m having it, but this happens a lot. I really oughta get an ADHD diagnosis lol
