I believe I tried that, but I must be doing something wrong with that angular momentum calculation.
How do you calculate the angular momentum of the mud before it hits the door? Is it (mass of mud * velocity of mud * distance from the hinge)? Since it hits at the middle, that distance would...
Homework Statement
A solid wood door of width 1.00 m and height 2.00 m is hinged along one side and has a total mass of 49.0 kg. Initially open and at rest, the door is struck at its center by a handful of sticky mud with mass 0.500 kg, traveling perpendicular to the door at 14.0 m/s just...
