1.	A rod AC Of length l and mass m is kept on a horizontal smooth plane. It is free to rotate and move. A particle of same mass m moving on the plane with velocity v strikes rod point B making angle 37^(@) with the rod. The collision Is elastic. After collision
Answer» The angular velocity of the ROD will be `(72V)/(55l)` The centre of the rod will TRAVEL a distance `(pil)/(3)` in the time which it makes HALF rotation. Impulse of the impact FORCE is `(24mV)/(55)` The centre of the rod will travel a distance `pi//8` in the time in which it makes `1//4`th rotation. Answer :A::B::C
