. Two bodies A and B of mass 150 g and 250 grespectively are approaching each other. Bothparticles have a speed of 3 m/s. Find the magnitudeof the total linear momentum of the system of thetwo particles. |

Answer» Mass of body A, ma= 150 g = 0.15 kg Mass of body B, mb= 250 g = 0.25 kg Both the bodies are moving towards each other. Let the direction of B be taken as positive. Then the direction of A will be considered negative. Velocity of A, va= - 3 m/s Velocity of B, vb= 3 m/s Now, total momentum of the system, P = mava+ mbvb => P = (0.15)(-3) + (0.25)(3) => P = -0.45 + 0.75 => P = 0.30 Ns |
