 (d) a. Since impulse is given to the body, so its momentum will increase and translation will occur. The impulse does not pass through the centre of mass. Hence, the dump- bell will rotate and its angular momentum will increase b. Here passes through centre of mass. So rotation does not occur and angular momentum remains zero c. This situation is similar to part (a) d. Here body is hinged.So translation does not occur, rotation will be there so angular momentum will increase Linear momentum increases as centre of mass of gains some velocity
