Bowling ball hits a pin, pin falls..which one has a greater force

I think that they are supposed to be equal (right?)...but why does the pin fall then?

Yes, the force of the ball on the pin is equal and opposite the force of the pin on the ball, so those force magnitudes are equal.

The pin falls because the force is large enough and high enough above the base of the pin that the resulting torque about the edge of the base is greater than the gravitational torque that would keep it upright.

You're welcome. I'm glad to help.
