I'm not currently taking physics but im curious as to the physics of a certain machine. You may or many not have seen it before, mostly in bars or clubs, there are punching bag machines. The best diagram i could draw is following. ______Top________________________________________________________________ | | | - / \ | | \__/ Any force would push the object in the left direction (<---) Now if you were to hit it in either the top or the bottom, I would like to know where the best place would be to hit it, in order to get the most successful hit which is measured by points im assuming by how hard the ball hits the sensor on the top. Any help would be greatly appretiated, and just let me know if I need to be more specific. Thanks in advance.
