So there is a rod standing straight up that gets hit with a ball of clay that sticks to it.
m=mass of rod
m/2=mass of clay
v=speed of clay
L=length of rod
3L/4=point where clay hits rod
I=(mL^2)/3=rotational moment of inertia of the rod about its end
g=gravity
point 0=center of mass of rod
1)Angular momentum of clay about point O
2)Angular momentum of clay and rod about point O
3)Moment of inertia of clay and rod after collision
4)Angular speed of the rod and clay about point O when the rod is vertically downward
5)Change in gravitational potential energy of the rod and clay as the rod goes from vertically upward to vertically downward
I have the answers but I don't know how to get them. Any help is appreciated.
