A disc is connected with a rod of mass m and length l. THe disc is free to rotate about its own axis. If whole system is rotating with omega1 j and disc also rotate about its own axis with omega 2 i then calculate L about origin.

A particle of mass `m` is projected with a speed `u` at an angle `theta` to the horizontal at time `t = 0`. Find its angular momentum about the point of projection `O` at time `t` respectively vectorially. Assume the horizontal and vertical lines through `O` as `X` and `Y` axes
