hi...can we consider P as a hollow cylinder then moment of inertia about the axis(which is passing through its centre) would be MR^2...AND THEN WE CAN CONSIDER Q AS A SOLID CYLINDER HAVING MOMENT OF INERTIA MR^2/2 (^2 MEANS SQUARE AND / DIVIDE)...SO IT MEANS MOMENT OF INERTIA OF P IS MORE THAN...
Two solid cylinders p and Q of same mass and same radius start rolling down a fixed inclinded plane from the same height at the asme time.cylinder P has most of its mass concentrated near its surface while Q HAS MOST of its mass near the axis...
THEN
1)WHICH HAS MORE MOMENT OF INERTIA AND...
hi,i have the similar problem...if i include the Earth in my system.EARTH HAS ZERO MOMENTUM before and after colision of car right? then acc to conservation of momentum MV+MV=0(WHERE M IS MASS OF CAR AND V IS VELOCITY OF CARS) then V=0?
