When you throw an irregularly shaped object, which part of the object follows the parabolic motion path?

So yea, I wasn't paying attention in class and had this on my homework. It's about center of motion and center of gravity. The full question is: When you throw an object which has an “L” shape (an irregular shape), what part of the object will follow the projectile motion parabolic path for the entire trip?

Center of mass or center of gravity?



Thanks in advance!When you throw an irregularly shaped object, which part of the object follows the parabolic motion path?I think the center of gravity because the center of mass is usually used in problems where the object is in deep space or something. Also I remember a lecture about how high jumpers can actually have their center of gravity at or under the bar they're trying to jump over, because of the way they align themselves.
