A uniform rod of mass m and length l rests on a smooth horizontal surface.One of the ends of the rod is struck in horizontal direction at right angles to the rod.As a result the rod attains a velocity v.Find the force with which one half of the rod will act on the other in process of motion

1well aragorn.... there are many like this.... even older...
if u turn the pages u will find ... [1]
24Such an unfortunate thing..........I too forgot about it...........
62arrey this is easy..
I will tell u the method... try this one..
1) take the rod as 2 masses..
2) The velocity of the end point of the 2 "rods" will the same... (i mean the two sub rods!)
3) The angular velocity will be the same
4) Draw an FBD of both the parts..
5) Analyse forces etc... Done :)
