A body of mass 5 kg moves along X-axis with 2ms^(-1) A second body of mass 10 kg moves along y-axis with velocity sqrt3 ms^(-1). They collide at the origin and stick together. The velocity of the combined mass is : |

Answer» `(4)/(3) ms^(-1)` Similarly `p_(2)=m_(2)u_(2)=10sqrt3 kg ms^(-1)` According to conservation of momnetum, `(m_(1)+m_(2))V=20` `implies v=(20)/(15)=(4)/(3) ms^(-1)` |
