I have been presented with this problem. I somewhat know what I need, I just don't know how to get it The problem: A truncated cone, top diameter of 1m bottom diameter of 1.5m and a height of 10m. With a given density(I do not have it with me at this moment, I do not remember exactly what that number is). Find the weight of the object and the force it would hit the groud with, I assume when falling over. I would like to know where, or if anyone knows, I can find the appropriate formulas for solving this. I have found how to get the volume of the object, and I can get the weight of the object. What I do not have any idea about is calculating the force the object hits the ground with when falling. I assume torque would have something to do with it, but I do not know what type of formulas to use or where to find them. Thanks for any help with this.
