A shell of mass 100 g moving with speed of 50 m s^(-1) along a straight line inclined at an angle tan^(-1) ((4)/(3)) to the horizontal bursts into two pieces. The piece of mass 60 g starts moving horizontally with a speed of 50 m s^(-1). The other piece moves with a speed of |

Answer» `50ms^(-1)` opposite to the first PIECE `= (100)/( 1000) xx 50kgms^(-1)=kgms^(-1)` Horizontalmomentum`= 3 kgms^(-1)` verticalmomentum`= 4 kgms^(-1)` thevelocityof otherpieceof mass40 g ` = (4 kgms^(-1))/( 0.04kg ) = 100MS^(-1)` Toconservemomentum ,itshouldbe directedvertucallydownward . |
