can I break a 1000 psi resistant glass with a water balloon with a 15 kg*m/s momentum?

Question

how do I verify that with physichs formulas?

Answer 1

What are the dimensions of the glass; tube, strip, sheet and what is your baloon made of and what is in it? At what temp. do you expect the glass to be - either very hot or very cold will shatter it. Gotta give more info.

Answer 2

For a simple analysis I'd assume that the collision zeros the momentum of the balloon by the time the balloon has traveled a distance equal to its radius R after initial contact. Also assume the minimum time t to travel this far (t=R/V, ignoring time increase due to deceleration) so the force (= 15/t) is maximum. (Note momentum m*V = impulse F*t.) Now assume an area less than the cross-sectional area of the balloon but not absurdly small; maybe 1/4 the balloon's area. This will give you a rough idea of the peak pressure (after you convert from Pa to psi).
I kind of question a strength expressed simply as a pressure. As the previous answer says, the dimensions are critical. A small pressure over a wide area and with a long lever arm could result in a large bending stress. Use judgment.
